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).

2GENERAL DESCRIPTION
1GENERAL DESCRIPTION
Features
Mitsubishi FR-A800/F800 safety stop function prevents a drive from supplying rotational energy to motors. Dual
safety channels ‘S1’ and ‘S2’ cut off the gate-drive power for IGBT to turn off.
Fig.1 FR-A800/F800 safety stop function diagram
Standards
Mitsubishi FR-A800/F800 safety stop function meets the following directives and categories.
ISO13849-1:2008 Category 3/PLd
IEC62061:2005 / IEC61800-5-2:2007 / IEC61508 SIL2
IEC60204-1:2010 / IEC61800-5-2:2007 Stop category 0
WARNING
Disconnecting the power to the gate driver by the safety stop function does not isolate electrically
between drive and motor. To avoid an electric shock hazard, disconnect power to the drive and verify
that the main circuit capacitor voltage is zero (across P and N terminals) before performing any work
on the motor (refer to your drive’s User Manual for discharging time).
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 directive.

2INSTALLATION AND WIRING
Installation
Mitsubishi FR-A800/F800 safety stop function should be used under following condition and environment.
Table.1 The condition and environment for using safety stop function
 The ND and HD ratings can be selected only for the FR-A800.
 Temperature applicable for a short time, e.g. in transit.
 For the installation at an altitude above 1,000 m (3280.80 feet) up to 2,500 m (8202 feet), derate the rated current 3% per 500
m (1640.40 feet).
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 FR-A800/F800 unit is mounted closely in enclosure meeting IP54
and all interconnection wiring is short and protected against open and short circuit faults. Refer ISO/

4INSTALLATION AND WIRING
●Wiring
The safety related terminals are described in Table.2 and Table.3
Table.2 The safety related terminals
 Specifications for conforming safety standards.
 ON: The transistor is conducted. OFF: The transistor is not conducted.
CAUTION
In order to meet safety stop, an approved safety relay unit to ISO13849-1 safety category 3 or better
shall be used in conjunction with FR-A800/F800 as shown in example. 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 for information) before performing any work on the drive. And 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
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’.

INSTALLATION AND WIRING 5
Table.3 Truth table of safety related signals
 ON: The transistor is conducted. OFF: The transistor is not conducted.
 When not using the safety stop function, short across terminals S1 and PC, S2 and PC, and SIC and SD to use the inverter.
(In the initial status, terminals S1 and PC, S2 and PC, and SIC and SD are respectively shorted with shorting wires.)
 If any of the protective functions shown in the following table is activated, the terminal SO turns OFF.
 If the internal safety circuit is operated normally, the terminal SO remains ON until E.SAF is displayed, and the terminal SO
turns OFF when E.SAF is displayed.
 SA is displayed when the terminals S1 and S2 are identified as OFF due to the internal safety circuit failure.
 If another fault occurs at the same time as E.SAF, the other fault can be displayed.
 If another warning occurs at the same time as SA, the other warning can be displayed.
NOTE
• The response time from safety stop signal input to drive shutoff (safe state) is faster than 8ms.
• Hold the ON or OFF status for 2ms or longer to input signal to terminal S1 or S2.
Signal input shorter than 2ms is not recognized.

 If the control logic is SINK logic, the common terminal is terminal SD.
Fig.3 Safety system example with FR-A800/F800
NOTE
• When starting up the system’s operation, press the RESET switch to reset the safety stop function first,
then turn ON the START switch to run the motor.
• In the above configuration, after reset of emergency stop button, drive will be in safe-state until RESET
switch is pressed.
CAUTION
To prevent restart in case of recovering from input power loss of drive, 3-wired connection for
START/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.
