Kinetix 5700 Safe Torque-off Function
Install 2198-xxxx-ERS4 Safety Connector Plugs
The safety connector plugs have two locking leavers that you push in a
clockwise direction as you insert the plugs into the drive connector. This is the
locked position. Rotate the leavers counter-clockwise to the open position to
release the connector plugs. This applies to 2198-
xxxx
-ERS4 single-axis and
dual-axis inverters.

-ERS4 Safety Connector Plugs
IMPORTANT
Push the locking leavers clockwise into the locked position as you insert
the STO connector plugs. Failure to do this can result in the connector
plugs pulling out of the drive connector during normal operation.

IMPORTANT
Pins ST0-1 and ST0-5 (SB+ and SB-) are used to disable the safe torque-off
function. When wiring to the STO connector, use an external 24V supply for
the external safety device that triggers the safe torque-off request. To avoid
jeopardizing system performance, do not use pin ST0-1 as a power supply
for the external safety device.
