According to the present description, two digital inputs have to be configured as
control signals to allow for external speed selection.

Device configuration M0053
I/O interface M0139
Digital inputs M0116
Example
Use inputs DIN 5 and DIN 6 as control signals for external speed selection:
Parameter:
Signal DIN 5 M0122
=
Speed int. sel. bit 0
Parameter:
Signal DIN 6 M0123
=
Speed int. sel. bit 1

Information
The logic for the digital inputs may be inverted. Depending on the parameter setting
(e.g.
Coding DIN 6 M0128
), the input is either
High active
or
Low active
. Default
setting is
High active
.
Configuration of analogue input for speed
For setting of parameter

Analogue input
.
An analogue input (AIN 1 or AIN 2) has to be configured as described to be able to
use an external (analogue) speed setpoint.

Example
Use analogue input AIN 1 for speed setpoint:
Parameter

Interface speed
Information
The speed range for the analogue input is determined via parameters
Speed rem.
min. M1936
and
Speed rem. max M1937

If the actuator is controlled via an external speed source, the internal speed values
described here will not have an impact on the operation behaviour.
