Enable (CTRL-

Behaviour can be parameterised.
–
Behaviour 1: The closed-loop controller can
only be enabled over the drive profile when
high level is present.
–
Behaviour 2: With a rising edge, the control-
ler is enabled without taking into account the
drive profile. The drive is energised and is in
the operating mode requested in the signal
transfer.
–
Behaviour 3: Enabling of the controller can
only be controlled over the drive profile.
If the request is withdrawn, the drive is braked
with a behaviour of the stop category 1. After the
braking ramp ends, the brake is engaged and the
output stage is switched off functionally.

Differential analogue input for typical input level
of ± 10 V
Through the analogue input, the following set-
point values and limits can be specified in the
form of analogue voltage:
–
Setpoint values for position, speed or
force/current
–
Limits for position or force/current
Yes

Internal design of digital inputs (DIN) - does not apply for STO inputs
The following equivalent circuit shows an example of the internal design of a digital input (DIN).
The digital inputs are designed for +24 V level corresponding to type 3 in accordance with EN 61131-2.
The digital inputs are not galvanically separated and have integrated EMC protective functions.
Two-channel safe inputs correspond in their internal design to two 1-channel inputs. But the equival-
ent circuit is not valid for the STO inputs. Information on 2-channel safe inputs
