Control Circuit Terminal Functions
NOTICE! The terminals HC, H1, are used for the Safe Disable function. Safe Disable can be
used to enable/disable the drive. Refer to Safe Disable Input Function on page 52
for details. Always remove the wire link between HC and H1 when using Safe
Disable.
NOTICE! The wiring length to terminals HC and H1 should not exceed 30 m.
NOTICE! When connecting a reactive load such as a relay coil to a photo coupler output,
attach a flywheel diode to the load (relay coil) like shown below. Ensure the diode
