Tips: Stepper linear actuator can normally start impulse frequency in no load conditions
Stepper motor linear actuator can normally start impulse frequency in no load conditions. If the pulse frequency is higher than the value, the motor can be started, but the lost step or a plug may occur. The start frequency should be lower in the load condition. If the motor is to be rotated at a high speed, the pulse frequency should have an acceleration process. The starting frequency is low and it then will reach the expected high frequency according to the fixed acceleration.
