Note:
Options that control the stopping of the motor (Soft Stop, Pump Stop,
Linear Speed, Braking) require the self-powered gate drivers to be pre-charged by
the current loop power supply. If this supply is not present, an alarm symbol will
appear at the upper right corner of the control module display, and the options
will be inhibited. When the motor is stopped, it will coast. If the supply is
restored, the alarm symbol will be cleared and the module will perform the
programmed sequence.

This parameter identifies the type of control present and is not user
programmable.
Braking Control
Slow Speed Select
Allows the user to program the slow speed that best fits the
application.
Low:

Slow Accel Current
Allows the user to program the required current to accelerate the
motor to slow speed operation.
0...450% of full load current
Slow Running Current
Allows the user to program the required current to operate the motor
at the slow speed setting.
0...450% of full load current
Braking Current
Allows the user to program the intensity of the braking current applied
to the motor.
