Description of the Crane Control Option ACP 6000
(as from software version 2.7)
The BERGES crane control option has been developed specifically for crane and trolley
travel applications.
The extensive crane control function includes working limit settings for the maximum and
minimum speeds as well as switching inputs for speed limitation in the limit switch or safety
limit switch area.
Two inverters are required for complete 2-axis control (crane and trolley travel), one for
each axis.
The parameter
81-PRGNO
(selection of special programs) permits the control terminals of
the ACP inverters to be switched from the standard function to the BERGES crane control
option. This is done by entering the number 430 in the parameter
81-PRGNO
.
The following types of contact are used for controlling the individual control inputs:
•
FWD = NO contact
•
REV = NO contact
•
R/J
= NO contact
•
PS1
= NC contact
•
PS2
= NC contact
•
PS3
= NC contact
•
ART = NC contact

Safety Measures
1) The frequency converter-operated lifting motor is monitored as far as possible by the fre-
quency converter. To prevent damage in the event of a fault occurring, an additional
safety switch is required for the brake control.
EXAMPLE:
The maximum frequency (parameter 23) has been programmed from 50 Hz to 100 Hz
or higher and the motor loses the torque in the weakening of the field; due to this, the
load can pass through. The damage occurring as a result can be prevented by additional
monitoring.
2) The network downtime of the frequency converter must be maintained until the terminal
“+24V” has attained 0 volt or the display of the converter has turned dark. The Inverter
protects itself from switching on frequently and turning off and is then operational again
after approx. 10 minutes.

Functional Description
FWD = Selection of direction of rotation clockwise.
Save speed.
Parameter selection: 31-FMIN
When this input is selected for the first time, the drive accelerates to the target frequency
entered in the parameter
31-FMIN
. Operation is continued with the just reached rotational
frequency during the acceleration and deceleration phases by activation of this input.
Only the limit switch speeds entered in parameters
34-F3
(inputs PS1 and PS2) and
33-F2
(input PS3) may lie below this speed in travelling operation. Simultaneous operation of the
control inputs FWD and REV means stop.
REV = Selection of direction of rotation counter-clockwise.
Save speed.
Parameter selection: 31-FMIN
