description
• You can adjust the offset of the external analogue velocity command sys-
tem including that the controller.
• The offset is about 0.3mV per unit of this parameter.
• There are two ways for adjusting the offset : (1) manual adjustment and (2)
automatic adjustment.
You can set-up the internal command velocity of 1st to 4th speed to Pr53 to
56 respectively in [r/min] unit, when the internal velocity set-up is enabled
with the parameter Pr05 (Switching of internal and external velocity set-up).
<Note>
The polarity (+/- sign) of the set values shows the polarity of internal
command velocities.
Pr56 defines the velocity limit at the torque control mode.
You can set-up the JOG speed in [r/min] at JOG trial run mode.
For details of JOG functions, see Trail run.

1) Manual adjustment
• when executing the adjustment with the driver alone,. Set-up the value with this parameter so that
the motor may not run, after entering 0V exactly to the velocity command input (SPR).
• when the position loop is composed at the controller side, set-up the value with this parameter so
that the error pulse may become to 0 at Servo-lock status.
2) Automatic adjustment
• For detailed procedure, see Details of Operation in Appendix.
• The results of the automatic adjustment will be automatically entered as the value of this parameter.
