[. . . ] When a motor is operating in the jog at set speed mode, its cooling capability is greatly reduced. Therefore, the running time of the motor is dependant on the motor current. If the jog at set speed will be used on a regular basis, the motor temperature should be monitored using a thermostat. The thermostat can be connected between the power and input terminal 1 of the JC13 terminal block on the RediStart Micro II computer card so that the starter will trip when a fault occurs. Alternatively, temperature monitoring devices, such as thermistors or RTDs can be used. This will prevent the motor from being overheated and inadvertently damaged. Due to the way the jog at set speed operates, the starter may require the installation of a 5% line reactor to eliminate harmonic problems being introduced into the power system. This is dependent on the size of the motor in relation to the capacity of the power system. Values Default The jog current is adjustable from 25% to 250% in 1% increments. Time (maximum time) Description The maximum time parameter sets the time limit for continuous operation in the jog at set speed mode. This parameter should be set to a value that doesn't allow the motor to be operated in the jog at set speed mode for such a length of time that damage to the motor can occur. The default value for the Stab Cnst parameter is 100%. Ramp#1 Tim Description The Ramp#1 Tim parameter sets the length of time that the D. C. The Ramp#1 Tim is adjustable from 0 to 120 seconds in 1 second intervals. The default value for the Ramp#1 Tim is 15 seconds. Values Default Ramp#2 Tim Description The Ramp#2 Tim parameter sets the length of time that the D. C. 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 61 5. 8 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.
