5.4.3 Torque single trigger
As shown in the figure below, when the drive receives the external start trigger signal, it first enters into the locking
process, in which the drive is subject to two restrictions, one is the maximum torque limit, and the other is the maximum
speed limit, when not accelerated to the maximum speed, the drive outputs at the set maximum torque, when the speed
reaches the maximum value, the torque limit is carried out, and as the load gradually increases and is influenced by the
resistance, the The motor speed gradually decreases, when the motor speed is low enough and lasts for a preset
duration, this action ends and waits for the next start trigger signal.
