1. General description Features Mitsubishi Electric FR-D700 safety stop function prevents a drive from supplying rotational energy to motors. (In this Instruction Manual, the STO (safe torque off) function specified in IEC 61800-5-2 is referred to as the safety stop function.) Dual safety channels ‘S1’...

4. Test and checking failure CAUTION To avoid systematic faults, a test even for faulty demands of the safety function has to be performed in order to check the correct function of the monitor signal. This test shall be carried out at system installation, any software changes, parameterization changes, and/or at least once per year.
