Showing the relationship between input frequency and the maximum torque(pull-in torque) capable of
starting the motor at that input frequency.
 
Showing the relationship between input frequency and the maximum torque(pull-in torque) obtainable by
synchronizing the motor rotation with that input frequency which is gradually increased from the pull-in
characteristic range after start of the motor.
 
The maximum frequency at which the motor can start and stop, synchronized with input signals under the
condition of no-load.
 
Difference between theoretical and actual step angle.
 
The maximum frequency at which the motor can rotate in synchronized with the input frequency which is
gradually increased toward the maximum response rate under the condition of no-load.
 
The responses of start, stop and rotation is possible in this area. The motor is driven without problems
as long as the operating point is found in this area
 
The response is possible without losing synchronization in this area when the load torque is added
above the frequency of pull-in area.
 
the rotation speed(frequency) of STEPPING MOTOR is normally expressed in pps(pulse per second).
The drive frequency and rotational speed has the following relationship. Rotational speed
(rpm : revolution per minute) = frequency(pps) * 60 sec. / (360도/single step angle)
