6167 Cdios Module V2.1 Commands

Addition to V2.0:

• Hold on enable configuration added, to hold the motor as soon it is enabled, and to hold it when using START/STOP commands
• GOTO speed in GOTO command changed (now full 16 bit value at another selector)
• a GOTO command in progress can be interrupted by another GOTO command (with different speed) (note)
• a GOTO command in progress can be set to change it's speed immediately or at a given position (note)
• 2 trajects introduced to perform automatic changing motor speed at different positions during a GOTO command (note)
• Store command cannot be given when the motor is running
• Internal RPM_Error value can be read, for diagnostic
• Current RPM, RPM_Error and current position can be automatically send by a timer

Note on interruptable GOTO command and trajects: these functions are only available when the Slope Profile parameter is set to 0

All CDIOS messages are presented as 8 bytes long. When variable length messages are selected, the part of the message that is not send over the CAN bus is represented in italic/light gray text.

All multibyte (16 / 32 bits) parameters are placed in the messages with the LSB first (little endian)

All data set with this command is stored in EEPROM after the 'Store Configuration Command', becoming the new power on default.

This command is only valid when the motor is not running.

Possible error message:

 

Error	Module ID	3	4	5	6	7	8
A2h	0 - 15	0	0	Error Status	0	0	0

Parameter	Bit	Description
Error Status	0	1 = Motor is running

  

This command causes the motor to move to the given 32 bits (signed) motor position, starts a traject or sets the motor speed for the next goto command
 

Command	Module ID	Selector	4	5	6	7	8
23h	0 - 15	0 - 5	Motor position or amount of steps				0
		6 - 7	Traject	0	0	0	0
		8	Next GOTO Speed		0	0	0
		9	Next speed change absolute motor position				0
		10	Change GOTO Speed		0	0	0

This command is only valid when the motor is not running.

 

Parameter	Bit	Description
Selector	0	Move motor absolute to the given position
	1	Write position into internal latch, motor will move after SYNC command (note 1) When a SYNC pulse is received without prior reception of the goto command with selector = 1, the motor state remains unchanged.
	2	Move motor relative, motor moves forward when given amount of steps is positive. New motor position is calculated by adding the amount of steps to the current position, as long this is in the motor position range of -2147483648 up to 2147483647 (motor will move to the limit)
	3	Write relative position into internal latch, motor will move after SYNC command (note 1) When a SYNC pulse is received without prior reception of the goto command with selector = 3, the motor state remains unchanged.
	4	Move motor relative, motor moves forward when given amount of steps is positive. New motor position is calculated by adding the amount of steps to the current setpoint (e.g. last GOTO position) position, as long this is in the motor position range of -2147483648 up to 2147483647 (motor will move to the limit)
	5	Write setpoint relative position into internal latch, motor will move after SYNC command (note 1) When a SYNC pulse is received without prior reception of the goto command with selector = 3, the motor state remains unchanged.
	6	Starts the execution of traject 0/1
	7	Starts the execution of traject 0/1, after the SYNC command (note 1)
	8	Sets the maximum speed for the next GOTO command.
	9	Sets the absolute motor position to change the motor speed. When an interruptable GOTO is running; - send a new GOTO speed with selector = 8. - send a speed change position with selector is 9. When this command is given and the current motor position is beyond the given speed change position (command given too late), the speed is changed immediately. In fact this is a subset of the internal traject function. This command is illegal when a traject is running or NO interruptable GOTO is running
	10	Immediately changes the motor speed of a running GOTO. This command is illegal when a traject is running or NO interruptable GOTO is running
Parameter	Range	Description
Motor Position	-2147483648 up to 2147483647	32 bits long integer
Traject	0 - 1	Defines the traject number to use
Speed	0 - 32767	Sets the maximum speed for the next GOTO command. This speed is checked against and clamped to the configured minimum and maximum speeds. When the speed is zero, the configured maximum speed is used. After power on or reset, the speed is set to zero.

When 'Slope Profile' is zero, GOTO commands can be interrupted by other goto commands to change the speed or direction...
Change the motor speed while a GOTO command is executing can be done in 3 ways;

1. Send the new speed with selector = 10
2. Preset the new speed with selector = 8 and set the motor position to start the change with selector = 9
3. Preset the new speed with selector = 8 and resend the GOTO command (with same or other GOTO position).

Command code 24h: Start

This command is used to control the motor motion 'manually'
Do not combine this command with the 'goto position' command.

After a start command the Hold status (status 4 bit 2) will be zero

 

Command	Module ID	3	4	5	6	7	8
24h	0 - 15	Selector	Direction	Option	MotorSpeed		0

This command is only valid when the motor is not running.

 

Parameter	Value	Description
Selector	0	Motor starts directly according to 'Direction' and 'Option'
	1	Motor starts after SYNC command (note 1)
Direction	0	Motor starts in Forward direction, if forward end switch is inactive or forward end switch checking is disabled
	1	Motor starts in Reverse direction, if reverse end switch is inactive or reverse end switch checking is disabled
Option	0	Motor starts and remains at minimum speed
	1	Motor starts at minimum speed and accelerates to maximum speed This option is allowed to be given when the motor already was started with option 0, however, direction has to be the same.
	2	Motor starts and remains at minimum speed until the forward (when direction if forward) or reverse (when direction is reverse) end switch is activated, even if end switch checking is disabled. The motor will run a bit further after the endswitch was activated.
	3	Motor will accelerate / decellerate from its current speed to the selected motor speed. MotorSpeed is zero; the motor will stop MotorSpeed < minimum speed; minimum speed is used MotorSpeed > maximum speed, maximum speed is used This option is not allowed to be given when the motor was already started with option 2 or the motor is performing a GOTO operation. Otherwise it can be given at any time.
	4	Motor starts and remains at minimum speed until the I (index) input becomes active. The motor position is set to zero. The motor probably will run a bit further after the I input became active.
	5	Enable the motor (it may run from now on). The current position will be transferred to the setpoint. When 'Hold On Enable' is set to 1, the motor position will be hold on the setpoint after this.
	6	Motor starts and remains at minimum speed until the I (index) and the Z (Zero) input are active. The motor position is set to zero. The motor probably will run a bit further after the inputs became active.
MotorSpeed	0 - 30000	Target MotorSpeed (Option = 3)

Motor Current	0 - 255	Measured motor current, resolution is 0.01A
Heatsink Temperature	0 - 100	Heatsink temperature in ºC, bit 1 of Status3 will be high when Heatsink Temperature > 81ºC (note)
RPM Error	-30000 - 30000	The difference between the (internal) desired motor speed and the actual motor speed. When RPM Error < 0 the motor runs too slow. When RPM Error > 0 the motor runs too fast .

Parameter	Description
All	Same format as in the 'Set event on motor status change mask' command

Possible error message: 

This command stores the current or the default I/O module configuration into internal EEPROM memory.
The configuration is restored from this memory after power on or a reset command.

The motor must be disabled when executing this command

The internal EEPROM erasing / programming takes 260 up to 750 milliseconds, then the reply message is send.
During programming I/O communication with this module is inhibited.

Sending a command will result in a general error message with errorcode = 8.

The confirmation reply message for this command is NEVER SUPPRESSED.
