Control Word in Crane Profile
Control word in Crane profile (parameter
512 = crane profile)
The control word is used for sending commands from
a master, eg. a PC, to a slave (frequency converter).

NB!:
In Crane profile bit 04 Q stop is the only choice
for logic OR, logic AND and logic BUS.
Bit 00, Load contact 1 inverse/No function
Bit 00 = "1" means no speed reduction.
Bit 01, Load contact 2 inverse/No function
Bit 01 = "0" leads to further descreased speed (
parameter 702) if bit 00 = "0". Otherwise it leads to
a Trip. Bit 01 = "1" means no speed reduction.

Bit 02, No function/Positioning
Makes the motor turn with reduced speed
according to parameters 106, Motor Nominal
Speed, and 205, Max. reference.
Bit 02 = "0" means no reduced speed. Bit 02
= "1" means reduced speed.

.
Bit 05, No function/Start lowering
Makes the motor turn to lower the load opposite of the
direction set in parameter 707, Hoist direction.
Bit 05 = "0" leads to a stop if bit 06 = "0". Bit 05 = "1"
leads to start if bit 06 = "0". Otherwise it leads to a stop.

Bit 06, No function/Start hoisting
Makes the motor turn to hoist the load according to the
direction set in parameter 707, Hoist direction.
Bit 06 = "0" leads to a stop if bit 05 = "0". Bit 06 = "1"
leads to start if bit 05 = "0". Otherwise it leads to a stop.
Bit 07, No function/Reset
Please refer to
Control word in FC profile
.
Bit 09, Gear low/Gear high
Enables gear low or high. Bit = "0" is low
gear. Bit = "1" is high gear.
