Installation and Start-up Guide for NMBP-01
This chapter describes how to program the ACS 600 drive for the Modbus
Plus communication.
The reader should be already familiar with how to program the drive parame-
ters using the CDP-311 Control Panel, and how the parameters are arranged in
groups. For details see the ACS 600 Programming Manual.
After installing and wiring the NMBP-01 Module to the ACS 600 drive, the
first step is to alert the drive that there is a communication module installed.
Before this communication option module is used, Parameter 98.2 COMM
MODULE must be changed from NO to YES.
After this, Parameter Group 51 can be programmed for the correct configura-
tion.
When Parameter 98.2 is set to YES, there are new selections available to Con-
trol Location parameters which are not described in the basic ACS 600 Pro-
gramming Manual.
The NMBP-01 Modbus Plus Module is completely configured through the
control panel. There are no internal DIP switches or jumpers to be set on the
NMBP-01 option module.
When the NMBP-01 module is connected to the drive and it receives its
power, the option module will read its setup parameters from the drive. Dur-
ing the initial power-up sequence, the Modbus Plus module configuration
information is set to default values, which can be changed from the control
panel.
