NB!
In par. 8-50
Coasting select
a selection is made to define how Bit 03 gates with the corresponding function on a digital input.
Bit 04, Quick stop:
Bit 04 = “0” causes a stop, in which the motor speed is ramped down to stop via 9ar. 3-81
Quick stop ramp time
.
Bit 05, Hold output frequency:
Bit 05 = “0” causes the present output frequency (in Hz) to freeze. The frozen output frequency can then be changed only by means of the digital inputs (par. 5-10
to 5-15) programmed to
Speed up
and
Speed down
.
NB!
If
Freeze output
is active, the frequency converter can only be stopped by the following:
•
Bit 03 Coasting stop
•
Bit 02 DC braking
•
Digital input (par. 5-10 to 5-15) programmed to
DC braking
,
Coasting stop
or
Reset and coasting stop.
Bit 06, Ramp stop/start:
Bit 06 = “0” causes a stop, in which the motor speed is ramped down to stop via the selected ramp down parameter.
Bit 06 = “1” permits the frequency converter to start the motor, if the other starting conditions have been fulfilled.
NB!
In par. 8-53
Start select
a selection is made to define how Bit 06
Ramp stop/start
gates with the corresponding function on a digital input.
Bit 07, Reset:
Bit 07 = “0” does not cause a reset.
Bit 07 = “1” causes the reset of a trip. Reset is activated on the signal's leading edge, i.e. when changing from logic “0” to logic “1”.
Bit 08, Jog:
Bit 08 = “1” causes the output frequency to be determined by par. 3-19
Jog speed
.
Bit 09, Selection of ramp 1/2:
Bit 09 = “0” means the ramp 1 is active (par. 3-40 to 3-47).
Bit 09 = ”1” means that ramp 2 (par. 3-50 to 3-57) is active.
Bit 10, Data not valid/Data valid:
Is used to tell the frequency converter whether the control word is to be used or ignored.
Bit 10 = “0” causes the control word to be ignored.
Bit 10 =”1” causes the control word to be used.
Bit 11, Relay 01:
Bit 11 = “0” Relay 01 not activated
Bit 11 = “1” Relay 01 is activated, provided
Control word Bit 11
has been chosen in par. 5-40
Function relay
