Danfoss VLT 5000 Operating Instructions Manual page 16

Bit 08, Jog 1 OFF/ON:
Activation of pre-programmed speed in parameter
509 (Bus Jog 1). JOG 1 is only possible when
Bit 04 = "0" and bit 00-03 = "1".
Bit 09, Jog 2 OFF/ON:
Activation of pre-programmed speed in parameter
510 (Bus Jog 2). JOG 2 is only possible when Bit
04 = "0" and bits 00-03 = "1". If both JOG 1 and
JOG 2 are activated (bits 08 and 09 = "1"), JOG 1
has the higher priority, which means that the speed
programmed in parameter 509 will be used.
Bit 10, Data not valid/valid:
Used for telling VLT 5000 whether the control word is
to be used or ignored. Bit 10 = "0" means that the
control word is ignored. Bit 10 = "1" means that the
control word is used. This function is relevant because
the control word is always contained in the telegram,
regardless of the type of telegram used, i.e. it is possible
to disconnect the control word if it is not to be used in
connection with updating or reading of parameters.
Bit 11, No function/slow down:
Used for reducing the speed reference by the
value in parameter 219. Bit 11 = "0" means that
there is no change of the reference. Bit 11 = "1"
means that the reference is reduced.
Bit 12, No function/catch-up:
Used for increasing the speed reference by the value of
parameter 219. Bit 12 = "0" means that the reference
is increased. If both slow down and catch-up are
activated (bits 11 and 12 = "1"), slow down has the
higher priority, i.e. the speed reference is reduced.
Bits 13/14, Choice of Setup:
Bits 13 and 14 are used for choosing among the
four menu Setups in accordance with:
Setup Bit 14
1 0
2 0
3 1
4 1
This function is only possible if Multi-Setups have
been selected in parameter 004.
