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
This instruction manual is compatible with FR-D700-SC-EC source-logic safety terminal model. For
FR-D700-EC sink-logic safety terminal model, refer to the FR-D700 safety stop function instruction
manual (BCN-A211508-000).

1. General description
Features
Mitsubishi Electric FR-D700-SC 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.

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-SC 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.

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 Measure the DC bus voltage at the P(+) and N(-) terminals or test

CAUTION
In order to meet safety stop, an approved safety relay unit to ISO13849-1/EN954-1 safety category 3 or better shall
be used in conjunction with FR-D700-SC as shown in example1,2.
In addition, all other components with in the safety stop loop shall be ‘safety approved’ types.
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’.

detection through RUN output.
For safety stop, configure the wiring as shown in Fig.3 above.
NOTE
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 PC for starting, ensure the compliance with safety requirement for the restarting when
the drive recover from input power loss.
• XS0 should be connected to RUN terminal and XS1 should be connected to SE, because polarity of
XS0 is positive, XS1 is negative.
• Pr.190 (RUN terminal function selection) must be set to "81". This setting makes the RUN output to
turn off in case of failure.
• The above wiring is configured to prevent restart in case of a fault.
• 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)
• After the power-up of the system, to reset the safety stop mode, press the START switch, and also
press the STF switch, then start the motor rotation.

• Pr.190 (RUN terminal function selection) must be set to "81". This setting makes the RUN output to
turn off in case of failure.
• Do not connect the FR-D700 (sink logic) together with the FR-D700-SC (source logic). If connected
together, the safety stop function does not work properly. (Refer to page 7.)

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.
I/O status and failure
FR-D700-SC safety related I/O status obeys the following truth table.
Table.5 Truth table of Safety related signals
Input power S1-SC S2-SC Internal safety
circuit *1 SO (SAFE) RUN (SAFE2) *2 Inverter operation state

"N/A " denotes a condition where circuit fault does not apply.
*1 At an internal safety circuit fault, one of E.SAF or E.CPU is displayed on the operation panel. SA is displayed on the operation
panel while S1 and S2 signals are both open and the safety function operates (without internal safety circuit fault).
*2 To use RUN terminal for monitor output of failure detection, Pr.190 should be set 81 (Safety monitor 2).
In case of diagnostic or functionality test, check the I/O state whether it is same or not as Table.5.
Diagnostic
If the failure detected, FR-D700-SC output alarm signal and indicate ‘E.SAF’ at the display.
In case of FR-D700-SC output the alarm, please take following action.
(1) Check the S1-SC and S2-SC input signal logic is the same. If these are different logic, correct the input
signal and reset the FR-D700-SC.
(2) Disconnect the wire from S1, S2, SC terminal, then reset or power-off and on, If the ‘SA’ letter is
flashed up at display, there is failure in system except FR-D700-SC. But, still ‘E.SAF’ is displayed and
alarm output, there is malfunction on FR-D700-SC.
Self diagnostic test
FR-D700-SC does the self-diagnostic test on the power-ON.
If FR-D700-SC output alarm at power-ON, please take the action described in ‘Diagnostic’ at above.

Test procedure for functionality
As depicted ‘ATTENTION’ in above, the test for the functionality is important.
Please do the test following procedure.
(1) Please make each state of S1-SC and S2-SC depicted at Table.5.
(2) If there is any different state from Table.5, FR-D700-SC has some malfunction.
(3) If there is no different state from Table.5, check the systematic performance, such as, press the
Emergency switch, press the start/restart button at the failure detected (RUN-SE opened), and so on.
(4) Finally clear the error record of the FR-D700-SC (see the user manual how to clear the error record).
