30 POSITIONING PARAMETER
30.2 Details of Parameters
Bias Speed
Setting method: High Speed I/O Parameter, Special Device
Set the lower limit (bias speed) for command speed, OPR speed, and creep speed. The user unit is set by unit setting.
(Page 385 Unit Setting)
The setting range is as follows.
Even within the setting range, the following relation must be followed: bias speed  command speed (OPR speed) 
maximum speed.
To control a stepping motor using each positioning instruction, set the bias speed considering the resonance range and the
self-starting frequency of the stepping motor.
■Special Device
Acceleration Time
Setting method: High Speed I/O Parameter, Special Device
Set the time required for acceleration from the bias speed to the maximum speed.
The setting range of acceleration time is 0 to 32767 ms. If command speed is slower than the maximum speed, the actual
acceleration time becomes shorter than the set time.
