1 INTRODUCTION The 374T000600V is a remotable display/keypad for OPD EXP and mini-OPD EXP drives. The reliable RS485 industrial standard interface allow the keypad to be remotated up to several hundred meters. It implements a Modbus RTU protocol and behaves like a master on the RS485 bus with the possibility to connect to several slave drives selecting the active drive (one at a time) by node address and bitrate.

For “long” and/or multidrop connection is also mandatory to connect the polarization/termination networks both on the first and last device on the bus chain: to do so, the pin 5 have to be tied with pin 2 (2 and 3 if the device is a drive) and the pin 9 have to be tied with pin 6 (6 and 7 if the device is a drive). Shielded cable with twisted pairs (min AWG 22) is also recommended To enhance EMI noise immunity, when remote keypad is used with mini-OPD EXP,...
Supply voltage has very wide input range (see specifications) and the keypad is protected against polarity reversal. The builtin DC-DC regulator (switching type) assures high efficiency and almost constant power comsumption over the whole voltage range Please notice that THERE IS NOT ISOLATION between power supply and the RS485 interface, so take care during installation to avoid voltage contentions and ground loops.
For OPD EXP it is an external adapter that connects to the “remote keypad” interface in the front panel of the drive (the integrated keypad is switched off when the adapter is inserted: only one segment will remain lit up to signal that the drive has power supply).
The Operator Interface is almost the same available by the keypad integrated into the OPD EXP or mini- OPD EXP drives, with same menus and navigation/editation key sequences and combinations (please refer to the drive User Manual for further information about the standard operator interface). Note that the operator Interface of the drive is available only when there is communication between remote keypad and the drive.
