ACM 400 S motor control unit
7 / 24
a) Cables
max 30m
, in order to avoid EMC effects.
Avoid parallel layout of signal cables with power or antenna cables, to avoid
coupling interference.
b) System (mains)
[X17], [X18]
The control unit power supply unit must be protected on site with an all-pole short-
circuit proof motor protection switch with maximum permissible tripping range of
2.5...4.0A! Dimension the supply lead according to the
power input
...
for the drive unit (max. 2000W)
for the control unit ( approx 8VA)
and all external devices connected to it (e.g. sensors, control stations, lighting
and signalling devices, etc.).
[X18] Connect a
230V system
to
terminals "L1 / N / PE”
.
The terminals
"L3" and "N" (terminals 7 and 8) must be jumpered!
[X17] Connect a
400V system
to
terminals "L1...3 / N / PE"
.
c) 400V motor (3~)
[X14]
The load tap of the motor control unit and 3-phase operation is designed for a max
motor output of
2000W / 400V
. However, a max
operating time of 25%
must not be
exceeded.
Connect the
motor
to
terminals 12...15
[X14].
The running direction switchover is determined by the motor terminals "V" and "U".
d) 230V motor (1~)
[X15]
The load tap of the motor control unit and 1-phase mode is designed for
max motor
output
of
1000W / 230V
.
Connect a
230V supply
to
terminals "L1 / N / PE"
[X18].
The terminals
"L3" and "N" must be jumpered!
Connect the
motor
to
terminals 12...14
[X15], as shown in the diagram. The running
direction switchover is determined by the motor terminals "V" and "U".
e) Limit switch
[X16]
Limit switch operation is absolutely necessary to detect the respective end position.
These can be e.g. roller or inductive limit switches, which are executed as
break-
contact elements
.
Connect the
limit switch
to
terminals 40...42
[X16].
