Programming
discharge is to be activated. Mains failure inverted
is active in the logical ‘0’ situation.
See also Mains fault/quick discharge on
page 66, if required.
NB!:
The frequency converter can be totally
damaged by repeating the Quick discharge
function on the digital input with mains
voltage connected to the system.
Pulse reference is selected if a pulse sequence
(frequency) of 0 Hz is used, corresponding to Ref
MIN
,
parameter 204. The frequency is set in parameter
327, corresponding to Ref
MAX
.
Pulse feedback is selected if a pulse sequence
(frequency) is selected as a feedback signal.
Select Encoder feedback, input A, if encoder
feedback is to be used after choosing Speed control,
closed loop or Torque control, speed feedback in
parameter 100. Set Pulse/rpm in parameter 329.
Select Encoder feedback, input B, if encoder
feedback is to be used with a 90° pulse to
register the direction of rotation.
Safety interlock has the same function as Coasting
stop, inverse, but Safety interlock generates the alarm
message "external fault" on the display when the
selected terminal is logic "0". The alarm message will
also be active via digital outputs 42/45 and relay outputs
01/04 if programmed for Safety interlock. The alarm
can be reset using a digital input or the [OFF/STOP] key.
Data change lock is selected if data changes
to parameters are not to be made via the control
unit; however, it will still be possible to carry
out data changes via the bus.
