Analogue set value input "S1" (Pink)
Via this input, using a set value in the range from 0-10 VDC, any speed set
value in the range from 0 to n
max
. can be specified in rpm. Blank (set value
voltage = 0 VDC), the motor remains at a standstill and attempts to control
the motor at maximum torque (holding torque) when there is an attempt to
move the drive. In the standard designs, n
max
. is defined as 4000 rpm. For
different design variants, refer to the respective product specifications for the
value for n
max
.
NOTE
For drives in the design with input "S1" (analogue set
value), the frequency set value input is not defined.
Æ
Do not connect input "F+".

Analogue set value input "S2" (brown)
Via this input, with a set value in the range of 0-5 VDC, the current limit can
be specified in the range from 0 (no torque, motor does not move, rotor runs
freely) to 100 % (maximum torque). Therefore, input "S2" must be connected
in order to operate the drive. The current limit configured via input "S2" works
equally for driving and for braking.

Frequency set value input "F+" (red-blue)
This input is available for drive versions with frequency set value only and is
used to specify a speed set value using a defined frequency signal. For
detailed information in this regard, refer to the product specification.
NOTE
For drives in the design with frequency set value input, the
input "S1" (analogue set value) is not defined.
Æ
Do not connect input "S1".
RS-485 interface "Data A" and "Data B" (white / green)
NOTE
The RS-485 interface is not available in the basic variants.
The interface is used for adapting drive parameters or software
variants at the factory.
Æ
Do not connect the RS 485 interface.
