OTOR CONFIG
The DG-Mini is compatible with a wide variety of AC induction motors. The motor must be a 3-phase asynchronous
motor. The voltage rating on the nameplate of motor should match the model of the DG-Mini. The FLA rating of the
motor should be less than the output current rating of the DG-Mini model.
Use the speed provided on the nameplate at 50Hz for the NP speed setting in the DG-Mini. See the NP Speed
description below for details on how to convert a motor’s nameplate speed to 50Hz if necessary.
These menus are used to configure the DG-Mini’s settings to match the connected motor.

Submenu Description:
NP Speed
This is the normal motor Speed at 50 Hz. The value is obtained
directly from the Motor’s name plate speed i.e. 1350rpm at 50Hz.
See the motor’s label for speed rating.
If the Motor’s name plate speed is listed for 50Hz then enter that
value, otherwise convert the nameplate speed to 50Hz based on the
equation below.
To convert a 60Hz speed rating to 50Hz divide by 1.2
Example: 1750 RPM at 60Hz/1.2 = 1458 RPM at 50Hz.
Gear Ratio
This is the number of motor revolutions per one full revolution of the
encoder.

NOTE
The controller will automatically set
the direction during a Quick Setup.
Normal No change

Both the Motor and encoder are reversed
V/F Open
This is the frequency at which maximum voltage is delivered to the
motor while opening.
V/F Close
This is the frequency at which maximum voltage is delivered to the
motor while closing.
Boost Open/
Boost Close
The Torque boost increases the voltage and thus the torque when the
frequency is below the V/F frequency.
If the boost is set too low the door may not move. If set too high
excessive current draw may occur resulting in permanent damage to
the controller or motor. Modify only if necessary.
