Bit 02, DC brake
Bit 02 = 0: DC braking and stop. Set braking current and
duration in parameter 2-01 DC Brake Current and
parameter 2-02 DC Braking Time.
Bit 02 = 1: Ramping, see parameter 3-41 Ramp 1 Ramp Up
Time.
Bit 03, Coasting
Bit 03 = 0: The frequency converter releases the motor
immediately (the output transistors are shut off), so that it
coasts to a standstill.
Bit 03 = 1: The frequency converter starts the motor when
all starting conditions are fulfilled.
NOTICE
Parameter 8-50 Coasting Select defines how bit 03 gates
with the corresponding function on a digital input.
Bit 04, Quick stop
Bit 04 = 0: A stop ramps down motor speed to stop via
parameter 3-81 Quick Stop Ramp Time.
Bit 04 = 01: The frequency converter starts the motor
when all starting conditions are fulfilled.
Bit 05, Hold output frequency
Bit 05 = 0: The present output frequency (in Hz) freezes. To
change the frozen output frequency, set the digital inputs
to [21] Speed up and [22] Speed down in
parameter 5-10 Terminal 18 Digital Input to
parameter 5-15 Terminal 33 Digital Input).
NOTICE
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 (parameter 5-10 Terminal 18 Digital
Input to parameter 5-15 Terminal 33 Digital
Input) programmed to DC braking, Coasting
stop, or Reset and coasting stop.
Bit 06, Ramp stop/start
Bit 06 = 0: A stop ramps down motor speed to stop via
the selected ramp-down parameter.
Bit 06 = 1: The frequency converter starts the motor when
all starting conditions are fulfilled.
NOTICE
Parameter 8-53 Start Select defines how bit 06 Ramp
stop/start gates with the corresponding function on a
digital input.
Bit 07, Reset
Bit 07 = 0: No reset.
Bit 07 = 1: Reset of trip. Reset is activated on the leading
edge of the signal, that is, when changing from logic 0 to
logic 1.
