4.3 Control element
4 Function Description
Functions when operated with a safety card:
 PL e (Cat. 4) and SIL CL 3 can be achieved.
 This input is not compatible with IEC 61131-2.
 Volt-free, reference earth is XGND
 STO1-ENABLE
The input STO1-ENABLE is not active, so does not need to be wired.
 STO2-ENABLE
– If the STO2-ENABLE input is open, no more power is transferred to
the motor. The drive becomes torque-free and runs down.
– STO single-channel with safety card PMCprotego S1 or
PMCprotego S2:
The input STO2-ENABLE must be connected directly to 24 V. The
2nd shutdown route is not needed.
– STO dual-channel with safety card PMCprotego S1:
The input STO2-ENABLE must be connected to the output
STO SIL3 on the safety card.
– If the safety function STO is not needed, STO2-ENABLE must be
connected directly to 24 V.

Operational readiness (X3B/14, 15)
Functions:
 The servo amplifier is ready for operation when the relay contact BTB
is closed.
 Operational readiness is not dependent on the ENABLE signal, I²t lim-
itation and braking threshold.
 If an error occurs, the relay contact opens. The output on the servo
amplifier switches off. The output is disabled and supplies no power.
 A list of error messages is available in the chapter entitled “Messages/
Errors”, under “Error messages”.
