Safe Stop

Operations and Monitoring

The X200 inverter can perform the “uncontrolled stopping by removal of the motor power” which is Stop Category 0, as defined in EN60204-1.

It is designed and approved suitable for the requirements of Safety Category 3 in EN954-1, which is a protection against restart, called Safe Stop.

Prior to integration and use of X200 Safe Stop in an installation, a thorough risk analysis on the installation must be carried out in order to determine whether the X200 Safe Stop functionality and safety category are appropriate and sufficient.

The Safe Stop function of X200 is activated by turning ON the hardware switch (S8) located on the control card. When the switch S8 is made ON and if the emergency signal (b-contact) is given to the terminal 3 of the logic terminal block, the inverter removes the power to the motor only by integrated hardware, not software performance stands in-between.

Total system comprises an inverter with AC motor and safety-tested external disconnecting device. The external disconnecting device must have been approved for at least safety category 3 according to EN954-1.

HIGH VOLTAGE: Dangerous voltage exists even after the Safe Stop is activated. It does NOT mean that the main power has been removed.

The X200 inverter complies to EN954-1	Switch S8
category 3. When you turn the switch S8 on	(Right side)
the control card, X200 shuts off the motor
power by hardware.

When the switch S8 is made ON, input terminal for the emergency signal and the terminal for the reset signal will be assigned automatically to terminal 3 and 4. At this moment the parameter C003 is changed to EMR and parameter C004 is changed to RS automatically, and cannot be changed manually. Following table shows the assignments of each terminal according to the switch S8 condition.
