The safety function is designed so that the safety stop function of category 0 (uncontrolled stop) speci-
fied in IEC 60204-1 is used to meet the safety standards of PLd under ISO 13849-1. Currently, this
product is under application for safety standards.
The safety input function allows the inverter output when current flows in both the terminals GS1 and
GS2.
When the safety input function is activated, in compliance with the above standards, the output transis-
tor operation of the inverter is stopped safely (by shutting off its output). As a result, the motor stops
with free run.
For details, refer to 7-10 Safety Function (Under Application for Standards) on page 7-97.
Note This inverter meets ISO13849-1 PLc when the EDM function is disabled.
With the inverter power supply turned off, turn ON the safety function selector switch. This automatically
allocates the Multi-function Input S3/S4 Selection (C003/C004) to 77 (GS1) and 78 (GS2). To enable
the EDM output (safety monitor output), turn ON the EDM function selector switch. This automatically
allocates the Multi-function Output P1 Selection (C021) to 62 (EDM).
Note When the safety function selector switch or EDM function selector switch is turned from ON to OFF, the
input/output terminals allocated to GS1/GS2 or EDM are reset to 255 (no: No allocation) and the input/out-
put operation selection settings keep NC contact.
