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".
Precautions for using a stepping motor
(1) For the system that uses a stepping motor, executing the S-curve
acceleration/deceleration may cause step-out.
Before using the S-curve acceleration/deceleration, confirm that step-out does
not occur.
(2) In the system that uses a stepping motor, the circular interpolation control
cannot be carried out.
Although setting the bias speed at start is required by the characteristics of the
stepping motor, the setting of the bias speed at start is disabled for circular
interpolation control.
Ensure to use a servomotor for both 2 axes when the circular interpolation
control is carried out.
