Description

UCD224A103 High voltage frequency conversion control board ABB automation module

Speed control mode The motor rotates at the given speed of the transmission. This mode can also be used when the estimated speed is used as feedback. Speed control mode can be used in both local control mode and external control mode. The speed control mode is only supported in vector motor control.  Torque control mode The motor torque rotates according to the set torque of the frequency converter. Torque control mode can be used in both local control mode and external control mode. The speed control mode is only supported in vector motor control.  Frequency control mode The motor rotates at the given frequency of the inverter. The frequency control mode can be used in both local and external controls. Frequency control mode is only supported in scalar control.

In addition to the above control modes, the following special control modes can be provided:
• Process PID control. Torque set value Speed set value Frequency set value PID vector motor control mode Scalar control mode Torque controller Frequency controller program function
• Scram modes OFF1 and OFF3: The drive stops along a defined deceleration ramp and the drive modulation stops.
• Point mode: When the point signal is activated, the inverter starts and accelerates to the defined rotation speed according to the defined acceleration.
• Pre-excitation: DC excitation before the motor starts.
Dc lock: The motor rotor is locked at or near zero speed under normal operation.
• Preheating (motor heating) : Keep the motor hot when the drive stops.
