Torque Control Mode; Frequency Control Mode; Special Control Modes - ABB ACS280 Firmware Manual



Torque control mode

In torque control mode, the motor torque follows a torque reference given to
the drive. Torque control mode is available in both local and external control
locations. It is supported in vector motor control only.
Torque control uses torque reference chain.



Frequency control mode

In frequency control mode, the motor follows the drive output frequency
reference. Frequency control is available in both local and external control
location. It is supported in scalar motor control only.
Frequency control uses frequency reference chain.

Special control modes


In addition to the above-mentioned operating modes, the following special
operating modes are available:
• Process PID control. For more information, see section
55
on page .
• 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
43
page .
• 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. For more information, see section
52
