bridge cranes and hoists.

● Two operating modes are implemented.

The signal level on input TL. 34/35 determines which of the two operating modes is active:
TL. 34 0...5 V = “0" motorized potentiometer mode (ground control)

TL. 35 jumper with TL. 30 (0V24)

● A comprehensive limit switch control monitors the preliminary and ultimate (operational) limit

switches along the distance of travel of the bridge crane or trolley. To this end, the binary inputs
TL. 48/49/50/51 are permanently assigned to limit switch monitoring (low active). Parameters
P603...P606 are therefore ineffective.

● External fault detection via TL. 36/37:

The analogue input is used for an “external fault” binary input signal, which is active when low.
TL. 36 0...5 V = “0" external fault

TL. 37 jumper to TL. 30
Note: If this signal input is not used, then TL. 36 - TL. 44 (+24V) and TL. 37 - TL. 30 must

Terminals X14:48 - X8:48 and X14:49 - X8:49 are OR’d internally, allowing terminals X14:48-49 or
X8:48-49 to be used alternatively.

An external voltage +24V can be applied directly to analogue inputs X2:34 and X7:36. The negative
output of the external power supply must be connected to 0V24 (TL. 30).

limit switches

If not all limit switch inputs (TL. 48/49/50/51) are used, the open inputs must be connected to +24V
(TL. 44) as otherwise the limit switch monitoring will signal a fault (→ Sec. 2.6 Fault signals).

1.6 Limit switch connection

The use of end-of-track limit switches for crane control is supported. Altogether four limit switch
inputs are available for monitoring the travel and the travel speed. ( → Sec. 1.4 Wiring diagram and
Sec. 1.5 Control inputs).

- CW ultimate limit switch TL. 48

- CW preliminary limit switch TL. 49

- CCW ultimate limit switch TL. 50

- CCW preliminary limit switch TL. 51

The limit switches must be installed along the distance of travel in accordance with Fig. 4. For safety
reasons the limit switches must be implemented as “low active”. When the inverter is enabled the
internal limitswitch monitoringfeature monitors whether bothpreliminary andultimate limit switches
are connected in accordance with the wiringdiagram (→ Sec. 1.4). Ifonly one of the twopreliminary
or ultimate limit switches is missing no fault signal is issued. The limit switches are not monitored
for correct connection.

If not all limit switch inputs (TL. 48/49/50/51) are used, the open inputs must be connected to +24V
(TL. 44) otherwise the limit switch monitoring will issue a fault signal (→ Sec. 2.6 Fault signals).
