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 directive.
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.
WARNING
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.
WARNING
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
If you are using a FR-D740-EC or FR-D740-CHT with serial number shown below, safety function does not
work according to safety standard. In such case please contact your sales person.

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.
CAUTION
Ensure the safety relay unit and the D700 unit is mounted closely in enclosure meeting IP54 and all
interconnection wiring is short and protected against open and short circuit faults.
Refer EN/ISO13849-2.
Installation
Mitsubishi 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

CAUTION
In order to meet safety stop, an approved safety relay unit to EN954-1 safety category 3 or better shall be used in
conjunction with D700 as shown in example1,2.
In addition, all other components with in the safety stop loop shall be ‘safety approved’ types.
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

And verify that the voltage on the bus capacitors has discharged before Measure 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
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.
Refer to ‘4. Test and checking failure’.

Fig.3 Safety system example 1 – STOP asynchronous with emergency stop button and fault
detection through A-C output.
For safety stop, configure the wiring as shown in Fig.3 above.
Note: the above wiring is configured to prevent restart in case of a fault.
The parameter No.192 (A,B,C terminal function selection) must be set to ‘81’. This setting makes the A-C
output to open in case of failure.
After the power-up, to reset the safety stop mode, press the START switch, and also press the STF switch,
then start the motor rotation.
In the above configuration, after reset of emergency stop button, drive will be in safe-state until START
switch is pressed.
CAUTION
To prevent restart in case of recovering from input power loss of drive, 3-wired connection for STF/STOP
control is recommended.
In case of 2-wire connection and using latching type switch to short between STF and SD/PC for starting,
ensure the compliance with safety requirement for the restarting when the drive recover from input power
loss.

NOTE
When using the safety stop function, do not connect the FR-D700 series manufactured in July 2010 or
before together with the one manufactured in August 2010 or later. If connected together, the safety
stop function may not work properly.
When the FR-D700 series manufactured in July 2010 or before must be used together, connect an
electronic component (diode) to the inverter output shutoff signals (terminal S1 and S2).
Refer to page 7 for the specification of the diode.

undesirable current. Refer to the following for the specification of the diode.
Diode type : P-N junction type (Do not use a Schottky barrier diode.)
Electronic specification - Peak reverse voltage (Vrrm) : 50V or more, Peak forward voltage (Vf) : 1V or less (at 5mA),
Effective forward current (If) : 100mA or more

Fig.6 Safety system example 2 – STOP synchronous with emergency stop button and fault
detection through RUN output.
For safety stop, configure the wiring as shown in Fig.6 above.
Note: the above wiring is configured to prevent restart in case of a fault.
XS0 should be connected to RUN terminal and XS1 should be connected to SE, because polarity of XS0 is
positive, XS1 is negative.
The parameter No.190 (RUN terminal function selection) must be set to ‘81’. This setting makes the RUN
output to turn off in case of failure.
After the power-up, to reset the safety stop mode, press the START switch, and also press the STF switch,
then start the motor rotation.
In the above Fig.6, wired example2, in the event of reset of ‘safe-condition’ the motor rotation will not occur
until STF is pressed.
(for normal ‘non-safety’ STF/STOP function, please refer to your drive’s User Manual)
CAUTION
To prevent restart in case of recovering from input power loss of drive, 3-wired connection for STF/STOP
control is recommended.
In case of 2-wire connection and using latching type switch to short between STF and SD/PC for starting,
ensure the compliance with safety requirement for the restarting when the drive recover from input power
loss.
