Terminal Function Description
Terminal SG No connection • Standard RS485, half duplex with Modbus protocol, baud
rate 1200, 2400, 4800, 9600 BPS.
Terminal D- RS-485 communication (-) • Twisted shielded pair should be used.
Connect shield to ground on the PLC/Computer side.
Terminal D+ RS-485 communication (+) • Terminals 4 & 5 must be wired to Control Supply for
operation in communication mode (refer to section
8.16
page 70 for wiring diagram).
• Up 32 units can be connected for Modbus RS485
communication. For reliable communication, units should
be installed in the vicinity of 200m maximum, from the first
to the last unit.
• Refer to section 4.7.9 page 42 for programming.
• Refer to Appendix A of this manual for Modbus protocol
manual.
Terminal 28 Thermistor input (T1) Thermistor input is programmable as a PTC or NTC type
thermistor. The trip value is adjustable between 1-10Kohm,
preset delay of 2 Sec.
Terminal 29 Thermistor input (T2) Connect thermistor and/or Analog output shield to ground
terminal.
Terminal 30 Ground Analog output (0-10VDC or 0-20mA or 4-20mA)
Terminal 31 Analog output (-) Reflects motor current and is related to 2xIm. i.e., Full scale
(10VDC or 20mA) is related to 2xIm.
Terminal 32 Analog output (+) Note:
Refer to section
5.7 page 51 for analog output PCB dip switch
setting.
• Refer to section 4.7.8 page 40 for Analog Output
programming.
• Refer to section 4.7.7 page 38 for Thermistor Type and
Thermistor Trip programming.
