Pr.7
Bias speed at start
Set the bias speed (minimum speed) upon starting. The bias speed has to be
defined to allow the motor to start smoothly especially when a stepping motor is
used. (A stepping motor will not start smoothly if a low rotation speed is instructed
at the beginning.)
The specified "bias speed at start" will be valid during the following operations:
• Positioning operation
• OPR operation
• JOG operation
Note that the bias speed should not exceed "
Pr.8
Speed limit value".
