[. . . ] The Ramp#2 Tim is adjustable from 0 to 120 seconds in 1 second intervals. The default value for the Ramp #2 Tim is 15 seconds. Values Default 54 5. 7 PROGRAMMING: Starter Setup - Tachometer Setup TLoss Dela (Tachometer Signal Loss Delay) Description The TLoss Delay time is the allowable time the starter will operate when a tachometer signal is lost. If the signal is lost, the starter will perform the action set by the TLoss Mode parameter. NOTE: Nuisance tachometer loss faults at start can be prevented by setting the initial current parameter to a value that allows the motor to begin rotating soon after a start is commanded. Values Default The TLoss Delay time parameter is adjustable from 0. 1 seconds to 90. 0 seconds in 0. 1 second intervals. The default value for the TLoss Delay time is 1. 5 seconds. TLoss Mode (Tachometer Signal Loss Mode) Description The TLoss Mode determines the starter's action if it has been detected the tachometer signal is lost. NOTE: If Current ramp or TruTorque ramp is selected, all values within these ramp profiles must be set for proper operation. NOTE: If Current ramp or TruTorque ramp is selected, and the tachometer signal is lost, the starter will shut down and automatically restart with the new starting mode. The new start mode will apply until a manual reset to Tach is performed. Values Default The TLoss Mode parameter can be set to Shut (shutdown), Curr (Current Ramp), or TT (TruTorque Ramp). The default value for the TLoss Mode is Shut. 55 5. 8 PROGRAMMING: Starter Setup - Decel Setup V Level #1 Description The V Level #1 parameter sets the starting voltage for the voltage ramp deceleration ramp profile. The Fault Dly parameter is adjustable from OFF, 0. 1 through 90. 0 seconds in 0. 1 second intervals. The default value for the Fault Dly parameter is OFF. Values Default Bypass Dly (Bypass Delay) Description The Bypass Dly parameter determines when the bypass contactor will drop after a power disturbance is sensed. The Bypass Dly parameter is adjustable from OFF, 0. 0 through 3. 0 seconds in 0. 1 second intervals. The default value for the Bypass Dly time is 0. 0 seconds. Values Default Sense Time Description The Sense Time parameter determines how long a power outage must exist before the micro will drop to a coast to stop, and wait for a valid line voltage before restarting. The Sense Time parameter is adjustable from 0. 01 through 0. 50 seconds in 0. 01 second intervals. The default value for the Sense Time parameter is 0. 05 seconds. Values Default 58 5. 10 PROGRAMMING: Starter Setup - TruTorque Ramp Int Torque (initial torque) Description The initial torque parameter sets the initial torque level that the motor will produce during starting. This parameter should be set to a level that allows the motor to begin acceleration with a few seconds of a start command being received. The default value for initial torque is 20%. Values Default Max Torque (maximum torque) Description The maximum torque parameter sets the final level of torque that is supplied to the motor during starting. For a loaded motor, the maximum torque parameter initially should be set to 100% or greater. If the maximum torque value is set too low, the motor may not produce enough torque to reach full speed (UTS). On a lightly loaded motor this parameter may be reduced below 100% to provide for smoother starts.
