WARNING! Sudden Movement Hazard. The logic of terminals DM+/DM- is inverted between drive models CIMR-LA and
CIMR-LF. Check all wiring to ensure that the sequence is correct after installing the drive and connecting any other devices.
Improper wiring connections could result in death or serious injury.
NOTICE: From the moment terminal inputs H1 and H2 have opened, it takes up to 1 ms for the drive output of models CIMR-LA
to shut off completely, or up to 3 ms for the drive output of models CIMR-LF to shut off completely. The sequence set up to trigger
terminals H1 and H2 should confirm that both terminals remain open for at least 1 ms in order to properly interrupt the drive output of
models CIMR-LA, or for at least 3 ms in order to properly interrupt the drive output of models CIMR-LF. This may result in
the Safe Disable Input not activating.
NOTICE: The Safe Disable Monitor (output terminals DM+ and DM-) should not be used for any other purpose than to monitor the Safe
Disable status or to discover a malfunction in the Safe Disable inputs. The monitor output is not considered a safe output.
NOTICE: When utilizing the Safe Disable function, use only the EMC filters recommended in
Using the Safe Disable Function

Note: Terminals H1, H2, DM+, and DM- on 600 V class models are designed to the functionality, but are not certified to IEC/EN
61800-5-2, ISO/EN 13849 Cat. 3, IEC/EN 61508 SIL2, Insulation coordination: class 1.
The Safe Disable inputs offer a stop function in compliance with "Safe Torque Off," as defined in IEC/EN 61800-5-2.
Safe Disable inputs have been designed to meet the requirements in
A Safe Disable Status Monitor for error detection in the safety circuit is also provided.
Safe Disable Circuit
Note: Terminals H1, H2, DM+, and DM- on 600 V class models are designed to the functionality, but are not certified to IEC/EN
61800-5-2, ISO/EN 13849 Cat.3, IEC/EN 61508 SIL2, Insulation coordination: class 1.
The Safe Disable circuit consists of two independent input channels that can block the output transistors (terminals H1
and H2). The input can either use the drive internal power supply or an external power supply. Use jumper S3 on the
terminal board to select between Sink or Source mode with either internal or external power supply.
A photocoupler output is available to monitor the status of the Safe Disable terminals DM+ and DM-.
Terminals on page 48 for signal specifications when using this output.
Additionally a Safe Disable monitor function can be assigned to one of the digital outputs (H2- = 58).
