LC - Control Setting Parameters
Integral speed control gain during acceleration and high speed.
Integral speed control gain during deceleration and low speed.
Integral speed control gain for pre-torque.
The pre-torque gain setting controls the rate of the build up of torque and
the stiffness of the motor as the brake releases. This gain can be adjusted
to control the strength of the pre-torque. In general lower spring tension and
lower brake pick voltages result in a smoother transition of the load from brake
to motor. This gain should be adjusted as high as necessary to prevent the
sheave from moving during brake release. Typical values are between 5,000
and 20,000. If the value gets too high, vibration or audible noise in the motor
may occur during the pre-torque phase.
Refer to Section 5.12.2 for additional information regarding pretorque.
