Chapter 7 – Fault Tracing
This chapter gives step-by-step diagnostics information for determining root
causes and corrections to the most usual problems with the NMBP-01 Mod-
ule.
This section is divided into different sections, and every chapter lists first the
symptoms, then possible causes, and remedies for them.
Installation Problems
Verify all the connections on the module:
•
Modbus Plus cable is connected to the Modbus Plus terminal
•
24 V d.c. power is connected to the power terminal
•
Fibre link cable is connected between the drive Channel 0 and the
NMBP-01 Module
•
Check that the fibre link connector colours match the drive and NMBP-01
Module connector colours.
Drive Setup
Group 51 is not shown on panel.
•
Set Parameter 98.2 to YES (COMM MODULE)
The NMBP-01 is using default values.
•
Verify that Parameter Group 51 is setup correctly. If so, press the configure
button on the NMBP-01 which causes the module to re-read its setup
parameters.
Drive values can be read, but the control (Start/Stop or Reference) does not go
through.
•
Check that the control location parameters are set to COMM. MODULE
for the required operation.
•
Check that the drive is in REMOTE control.
