Troubleshooting
Chapter Objectives Chapter 12 provides information to help troubleshoot your
1336 IMPACT drive.
During the start-up procedure, you should have recorded board
jumper settings for each board, board software version numbers, and
the drive and motor nameplate data in Table 6.A. If this information
was not recorded, record it before beginning any troubleshooting
sequences.
Required Equipment For initial troubleshooting, you need a programming device to read
fault codes. You should also have the following equipment available
before starting any troubleshooting procedures:
• digital multimeter (DMM) capable of 1000V DC/750V AC, with
one megohm minimum input impedance
• clamp on ammeter (AC/DC) with current ratings to 2X rated
current output of the 1336 IMPACT AC drive
• dual trace oscilloscope with differential capability, digital storage,
two X10 and one X100 calibrated probes (optional but
recommended)
