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 41
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.
