VIX IM MICROSTEPPER INDEXER DRIVE USER GUIDE
62
You do not have to wait for the IP flag to be set at the end of every move, but its use
improves positioning accuracy.
Example Use this code after each G command to improve positioning.
1MI ; mode incemental
1W(CQ,0) ; turn off command queuing
1G ; start the move
1T0.1 ; wait 100ms
1IF(MV,=,1)
1”Moving”
1TR(IP,=,1)
1”Stopped”
1W(CQ,1) ; re enable command queuing
HF Description
HF sets the final home velocity when you perform a GH command.
IC Description
See IC System Variable in the Electrical Installation section.
IN Description
The IN system variable is equivalent to the IS command, but allows individual inputs to be
tested using IF and TR commands during conditional coding.
For example:
The following test looks for input 1 low and input 3 high.
IF(IN,=,0X1XX)
Where X=don’t care.
INn Description
The INn system variable is used to define a particular bank of inputs when used with
Fieldbus input expansion modules.
MS Description
When the motor is stationary, reduce its current to minimise heating or to conserve power.
MS sets the reduction in current as a percentage of the programmed current (the value set in
the MOTOR command). When selected, the drive will switch to standby 25mS after the last
motor step.
Motor standby current reduction is capped at a value of 70% of the drive’s maximum output
current. Consequently, if you attempt to set an MS value greater than 70 the current
reduction value will always be equal to 70% of the drive’s maximum output current. For
example, using a ViX500 (max. output current of 5.6A) and setting MS to 90 will give a
current reduction value of 4A (70% of 5.6A).
