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".
