Reversal of speed command input
Specify the polarity of the voltage applied to the analog speed command (SPR).
[+ voltage] [+ direction] [- voltage] [-direction]
[+ voltage] [- direction] [- voltage] [+direction]
Caution: When you compose the servo drive system with this driver set to velocity control mode and
external positioning unit, the motor might perform an abnormal action if the polarity of the speed
command signal from the unit and the polarity of this parameter setup does not match.
Set up internal command speeds, 1st to 8th
Set up acceleration/deceleration processing time in response to the speed command input.
Set the time required for the speed command(stepwise input)to reach 1000r/min to Pr3.12
Acceleration time setup. Also set the time required for the speed command to reach from 1000r/min
to 0 r/min, to Pr3.13 Deceleration time setup.
Assuming that the target value of the speed command is Vc(r/min), the time required for
acceleration/deceleration can be computed from the formula shown below.
Acceleration time (ms)=Vc/1000 *Pr3.12 *1ms
