NOTICE: The terminals HC, H1, H2 are used for the Safe Disable function. Safe Disable can be used to enable/disable the drive. If
special requirement are fulfilled, it can also be utilized for reducing the number of motor contactors to one. Refer to
Function on page 48 for details. Always remove the wire link between HC, H1, or H2 when using Safe Disable.
NOTICE: The wiring length to terminals HC, H1 and H2 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 rating is greater than the circuit voltage.
