Control Word Under Vlt Standard - Danfoss VLT 5000 Operating Instructions Manual

Control Word under VLT standard

(parameter 512 = FC Profile). The control word is
used for sending commands from a master (e.g. a
PC) to a slave (VLT frequency converter).

Bit 00/01: Bits 00 and 01 are used for choosing among
the four pre-programmed references (parameters
215-218) in accordance with the following table:
Preset ref. Parameter

NB!:
Parameter 508 is where to choose the way
bits 1/12 are to be combined (gated) with the
corresponding function on the digital inputs.

Bit 02, DC Brake:
Bit 02 = "0" leads to DC braking and stop. Braking
current and duration are set in parameters 125 and
126. Bit 02 = "1" leads to ramping.
Bit 08, Activation of Jog speed in parameter 213:
Bit 08 = "0": Jog speed not activated. Bit 08 = "1"
means that the motor is running at Jog speed.
Bit 09, Choice of ramp 1/2:
Bit 09 = "0" means that ramp 1 is active (parameters
207/208). Bit 09 = "1" means that ramp 2
(parameters 209/210) is active.
Bit 11, Relay 01:
Bit 11 = "0": Relay 01 not activated. Bit 11 =
1: Relay 01 activated, provided Control word bit
has been chosen in parameter 323.
Bit 12, Relay 04:
Bit 12 = "0": Relay 04 has not been activated. Bit 12
= "1": Relay 04 has been activated, provided Control
word bit has been chosen in parameter 326.
See the description of other bits under control
word for Profidrive standard.
NB!:
Unless otherwise mentioned, the control
word bit is combined (gated) with the
corresponding function on the digital
inputs as a logical "or" function.
