TH1A

Thermistor

Connection to motor thermistor

It is good practice to protect motors by using

 

 

 

thermistors. A typical resistance (up to a

 

 

 

reference temperature of 125_C) is 200,

 

 

 

rising rapidly to 2000

above this temperature.

TH1B

Thermistor

Connection to motor thermistor

Connect devices in series between TH1A and

 

 

 

 

 

 

TH1B. Jumper TH1A and TH1B if temperature

 

 

 

sensors are not used.

Parameter Settings (for Keypad Operation)

The factory settings should be sufficient to operate the control using the “Local” mode with the keypad. Only a few changes to the motor data parameters must be made. Before any parameters can be changed, set System::Configure I/O::Configure Enable to enable. All LEDs will blink during configuration. After parameter values are changed to meet the needs of your application, be sure to set System::Configure I/O::Configure Enable to Disable and do the Parameter Save procedure.
