With external control mode and multi-speed control. Two relays control forward rotation and reverse rotation respectively, and two relays control 15HZ and 50HZ respectively (the frequency value is preset in the multi-speed parameter first. Pay attention to wiring, the relay will control which speed is set.

These parameters use factory default values. If it is difficult to start, adjust the torque compensation upwards and try. At the same time, consider slightly increasing the startup frequency.

Slip compensation is generally not used.

Linear acceleration can be used, but the set value of acceleration and deceleration should be set according to the actual requirements on site. If the commutation time is short, it is necessary to reduce the deceleration time.

If there is no special requirement, you can always use the default value.
