5 Installation Procedure
◆
Prior to Installing the Option Unit
Prior to installing the CANopen Option, wire the drive and make necessary connections to
the drive terminals. Refer to the Yaskawa drive manual for information on wiring and
connecting the drive. Verify that the drive runs normally without the option installed.
◆
Installing the CANopen Option
Remove the front cover of the drive before installing the CANopen Option. Follow the
directions below for proper installation.
1. Switch off the power supply to the drive.
DANGER! Electrical Shock Hazard - Do not connect or disconnect wiring while the power is on. Failure to
comply will result in death or serious injury. Before installing the CANopen Option, disconnect all power to
the drive. The internal capacitor remains charged even after the power supply is turned off. The charge
indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To prevent electric shock, wait at
least five minutes after all indicators are off and measure the DC bus voltage level to confirm safe level.
2. Remove the front cover.
The original drive front cover may be discarded because it will be replaced by the CANopen
Option cover in step 8.
