Speed Control Mode; Torque Control Mode; Frequency Control Mode; Special Control Modes - ABB ACS580 Firmware Manual



Speed control mode

The motor follows a speed reference given to the drive. This mode can be used either
with estimated speed used as feedback.
Speed control mode is available in both local and external control. It is supported in
vector motor control only.


Torque control mode

Motor torque follows a torque reference given to the drive. Torque control mode is
available in both local and external control. It is supported in vector motor control
only.


Frequency control mode

The motor follows a frequency reference given to the drive. Frequency control is
available in both local and external control. It is supported in scalar motor control only.


Special control modes

In addition to the above-mentioned control modes, the following special control
modes are available:
• Process PID control. For more information, see section
111).
• Emergency stop modes OFF1 and OFF3: Drive stops along the defined
deceleration ramp and drive modulation stops.
• Jogging mode: Drive starts and accelerates to the defined speed when the
jogging signal is activated. For more information, see section
• Pre-magnetization: DC magnetization of the motor before start. For more
information, see section
• DC hold: Locking the rotor at (near) zero speed in the middle of normal operation.
For more information, see section
• Pre-heating (motor heating): Keeping the motor warm when the drive is stopped.
