Safety Stop Function Instruction Manual

Compliance with the EU Machinery Directive – Functional Safety
WARNING
Any misuse of safety function could lead to personal injury or death, property damage, or economic loss.
To ensure that the system complies fully with requirement of safety, make a system-level risk
assessment. Mitsubishi Electric Co. cannot assume responsibility for any system to comply with safety
standards.
To avoid an electric shock hazard, verify that the voltage on the bus capacitors has discharged before
performing any work on the drive. Measure the DC bus voltage at the P(+) and N(-) terminals or test
points (refer to your drive’s User Manual for locations and discharging time). The voltage must be zero.
The safety stop function do not isolate electrically between drive and motor. To avoid an electric shock
hazard, disconnect/isolate power to the drive and verify to ensure that the voltage is zero before
performing any work on the motor (refer to your drive’s User Manual for discharging time).
CAUTION
The information of this manual is merely a guide for proper installation.
Mitsubishi Electric Co. cannot assume responsibility for the compliance or the noncompliance to any
code, national, local or otherwise for the proper installation of this equipment.
A hazard of personal injury and/or equipment damage exists if codes are ignored during installation.
CAUTION
If you are using a FR-D740-EC with serial number shown below, safety function does not work
according to safety standard. In such case please contact your sales person.

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’ and ‘S2’ cut off the gate-drive power for IGBT to turn off.

WARNING
The safety stop function doesn’t isolate electrically between drive and motor. To avoid an electric shock
hazard, disconnect power to the drive and verify that the voltage is zero before performing any work on
the motor (refer to your drive’s User Manual for discharging time).
Standards
Mitsubishi Electric FR-D700 safety stop function meets the following standards and categories.
ISO13849-1:2015 Category 3/PLd (applies to the FR-D700 manufactured in January 2012 or later)
IEC62061:2021 / IEC61800-5-2:2016 / IEC61508:2010 SIL2
IEC61800-5-2:2016 Stop category 0
WARNING
The misuse of safety function leads to personal injury or death, property damage, or economic loss. To
ensure that the system complies fully with requirement of safety, make a system-level risk assessment.
Mitsubishi Electric Co. cannot assume responsibility for any system to comply with safety standards.

2. Installation and wiring
CAUTION
The following information is merely a guide for proper installation.
Mitsubishi Electric Co. cannot assume responsibility for the compliance or the noncompliance to any
code, national, local or otherwise for the proper installation of this equipment.
A hazard of personal injury and/or equipment damage exists if codes are ignored during installation.
Ensure the safety relay unit and the FR-D700 unit is mounted closely in enclosure meeting IP54 and all
interconnection wiring is short and protected against open and short circuit faults.
Refer to EN/ISO13849-2.
Installation
Mitsubishi Electric FR-D700 safety stop function should be used under following condition and
environment.
Table.1 The condition and environment for using safety stop function
Item Condition
Temperature
range
Operation -10°C to +50°C (non-freezing)
Storage -20°C to +65°C
Ambient humidity 90%RH maximum (non-condensing)
Vibration 5.9m/s2or less
Altitude maximum 1000m
Atmosphere Indoors (without corrosive gas, flammable gas, oil mist, dust and dirt etc.)
Over voltage category II or less
Pollution degree II or less
Mounting wall mounting / vertical orientation
WARNING
To avoid an electric shock hazard, insert the magnetic contactor (MC) between power source and drive.
Open the contact of MC and keep away from drive for discharging time (refer to your drive’s User
Manual for information) before performing any work on the drive. Verify that the voltage on the bus
capacitors has discharged before measuring the DC bus voltage at the P(+) and N(-) terminals or test
points (refer to your drive’s User Manual for locations). The voltage must be zero.
CAUTION
In order to meet safety stop standards, an approved safety relay unit to ISO13849-1/EN954-1 safety category 3 or
better shall be used in conjunction with FR-D700 as shown in example1 or 2.
In addition, all other components with in the safety stop loop shall be ‘safety approved’ types.
To avoid systematic faults, a test to check the operation 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.
Refer to ‘4. Test and checking failure’.
