Speed Control Mode - 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.
Speed control uses speed reference chain. Select speed reference with parameters
in group 22 Speed reference selection

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.
Torque control uses torque reference chain. Select torque reference with parameters
in group 26 Torque reference chain

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.
Frequency control uses frequency reference chain. Select frequency reference with
parameters in group

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
99).
• 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.
