82 Digistart D3: User Guide
Issue: G
12K – Adaptive Stop Profile-2
Options: Early Deceleration
Constant Deceleration (default)
Late Deceleration
Description: Selects which profile the Digistart D3 will use for an Adaptive Control soft stop.
12L – Adaptive Control Gain-2
Range: 1% - 200% Default: 75%
Description: Adjusts the performance of Adaptive Control. This setting affects both starting and stopping control.
12M – Brake Torque-2
Range: 20% - 100% Default: 20%
Description: Sets the amount of brake torque the Digistart D3 will use to slow the motor.
12N – Brake Time-2
Range: 1 - 30 (seconds) Default: 1 second
Description: Sets the duration for DC injection during a braking stop.
8.8.14 Group 13 - Slip Ring Motors
13A – Motor 1 Ramp
Options: Single Ramp (default)
Dual Ramp
Description: Selects whether to use a single or dual current ramp profile for soft starting. Set to single ramp for
non-slip ring induction motors, or dual ramp for slip-ring induction motors.
13B – Motor 2 Ramp
Options: Single Ramp (default)
Dual Ramp
Description: Selects whether to use a single or dual current ramp profile for soft starting. Set to single ramp for
non-slip ring induction motors, or dual ramp for slip-ring induction motors.
Pr 13B selects the ramp configuration for the secondary motor.
13C – Slip-Ring Retard
Range: 10% - 90% Default: 50%
Description: Sets the level of conduction after the rotor resistance contactor closes, as a percentage of full
conduction.
Set so that no current pulse occurs, but the motor retains enough speed to start correctly.
13D – Changeover Time
Range: 100 - 500 (milliseconds) Default: 150 milliseconds
Description: Sets the delay between the rotor resistance relay closing and the low resistance current ramp
starting. Set so that the contactor has enough time to close, but the motor does not slow down.
Pr 13D only applies if Pr 13A or 13B is set to 'Dual Ramp', and an output relay is set to
'Changeover Contactor'.
