Introduction; Troubleshooting Check List - YASKAWA CIMR-E7 series Technical Manual

Introduction

The following is a short guide to troubleshooting the L
diagnosing and correcting issues associated with the startup and operation of a drive with a industrial network. While most of the information is
centered on the application of the drive, the guidelines presented are applicable to most L
Diagnosis of network fault issues typically fall into three categories: installation, wiring and cabling, and network configuration. Installation and
wiring will be discussed below to help resolve common problems associated in L
documentation that accompanied the controller for information on system setup.

Troubleshooting Check List

1: The drive operates correctly without the
keypad. Check that the drive responds to commands and faults as the application requires.
2: Check that the
card hold down is on top of the L
3: Check that the communications cable plug end has been firmly seated in connector J1 on the
has been properly connected to the
that the cable
4: Check that the termination switch on the drive's terminal assembly is in the ON position.
5: Check that the communications cable is not routed near any high voltage or current wires.
6: Check that the
7: Check that the drive communications, command and control parameters are set correctly.
8: Check that the
fault message is displayed on the drive operator.
9: Check that the
oscilloscope. Make sure that the correct equipment is used and that it does not induce noise into the network. A Z-Lead probe
attachment for the oscilloscope is recommended. Also, when using line powered equipment, differential probes must be used in
order to avoid introducing imbalances onto the network.
Option ground connection unconnected.
10: If a safety interlock is used with the drive, verify that the safety interlock is wired properly and that the controlling
multi-function input parameter is programmed correctly.
11: Verify that the LEDs on the
11: Check that all other devices on the network are connected properly.
12: Check that the network is correctly terminated for the topology used.
13: Check that the node has been correctly configured. Refer to the documentation that was supplied with the
L W controller for information on node commissioning and configuration. The External Interface File (E7_LW.XIF) and

the Device Resource Files (E7_LW.TYP, E7_LW.ENU, E7_LW.FPT, and E7_LW.FMT) may be found on the CD supplied with
the drive or downloaded from www.drives.com.
