A. Reference
B. Speed
AU control may be used with control device with an output in the range of 0 V – 10 V (for example radio
or PLC).
PO control may be used with a controller with potentiometer.
The operation is as follows:
• Driving command S1 or S2 is given separately and means “drive minimum speed”
• The speed linearly follows the analog input signal.
2.7 Slowdown-limit operation
The slowdown function is available in MS2- (slow-lim), EP2- (slow-lim), EP3- and AU-control modes. It
can reduce maximum frequency at the both ends of the crane runway. When the function is active, the
reference slowdown frequency is set automatically by parameter P1.1.8 “Multistep freq2/Slowdown”.
The action in slowdown-limit area depends on parameter P1.5.1 “Slowdown Mode” settings. The
description on “Slowdown Mode” selections is shown as follows:
Parameter value Action
0 = Slow
When the limit switch circuit is opened, the maximum speed is limited in both directions until the limit switch circuit is
closed.
1 = Fast When the limit switch circuit is opened during running the slowdown function is activated and the maximum speed is limited
in the present running direction. If the limit switch circuit is open when power is turned on, the maximum speed is limited in
both directions until the limit switch circuit is closed.
2 = Fast power up When the limit switch circuit is opened during running the slowdown function is activated and the maximum speed is limited
in the present running direction. When power is turned off, the limit switch status is saved in EEPROM. When power is
turned back on and limit switch circuit is open, driving is allowed the maximum speed in opposite direction.
