Bit 02, DC brake
Bit 02 = 0 leads to DC braking and stop. Braking current
and duration are set in B-01 DC Brake Current and B-02 DC
Braking Time. Bit 02 = 1 leads to ramping.
Bit 03, Coasting
Bit 03 = 0 causes the frequency converter to immediately
"let go" of the motor (the output transistors are "shut off"),
so that it coasts to a standstill.
Bit 03 = 1 enables the frequency converter to start the
motor if the other starting conditions have been fulfilled.
NOTE
In O-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 C-23 Quick Stop Decel 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 (E-01 Terminal 18
Digital Input to E-06 Terminal 33 Digital Input) programmed
to Speed up and Speed down.
NOTE
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 (E-01 Terminal 18 Digital Input to
E-06 Terminal 33 Digital Input) 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.
NOTE
In O-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 signals leading
edge, i.e. when changing from logic "0" to logic "1".
