How to Program
Motor check [2]
Pre-magnetizing [3]
DC Voltage U 0 [4]
Function:
Select the drive function after a stop command or
after the speed is ramped down to the settings in
par. 1-81 Min Speed for Function at Stop [RPM].
Select Coasting [0] to leave the motor in free mode.
Select DC hold [1] t o energize the motor with a
DC holding current (see par. 2-00).
Select Motor check [2] to check if a motor
is bee n connected.
Select Pre-magnetizing [3] to build up a magnetic
field w hile the motor is stopped. The motor can
now produce a q uick torque build-up at start.
1-81 Min Speed for Function at Stop [RPM]
Range:
0-600RPM
*
1RPM
Function:
Set the speed at which to activate p a r.
1-80 Function at stop.
1-82 Min Speed for Function at Stop [Hz]
Range:
0.0-500Hz
*
0.0 Hz
Function:
Set the output frequency at which to activate
par. 1-80 Function a t stop.
1-83 Precise Stop Function
Option:
*
Precise ramp stop [0]
Counter stop with reset [1]
Counter stop without reset [2]
Speed compensated stop [3]
Speed compensated counter stop
with reset [4]
Speed compensated counter stop
without reset [5]
Function:
Select Precise ramp stop [0] to achieve high
repetitive precision at the stopping point.
Select Counter stop (with or without reset) to
run the adjustable frequency drive from receipt
of a pulse start s ignal until the number of pulses
programmed by the user in pa r. 1-84 Precise
Stop Counter Value has been received at input
terminal 29 or input terminal 33.
An internal stop signal will activate the normal
ramp-down time (par. 3-4 2, 3-52, 3-62 or
3-72). The counter function is activated (starts
timing) at the edge of the start sign al (when
it change s from stop to start).
Speed-compensated stop [3]: To stop at precisely
the same point, regardless of the present speed,
the stop signal is delayed internally when the
present speed is lower than the maximum
speed (set in par. 4-13).
Counter stop and Speed-compensated stop can
be combined with or without reset.
Counter stop with reset [1]. After each precise
stop, the number of pulses counted during
ramp-down 0 rpm is reset.
Counter stop without reset [2]. The number of
pulses counted during ramp-down to 0 rpm is
deducted from the c ounter value in par. 1-84.
This parameter cannot be adjusted while
the motor is running.
1-84 Precise Stop CounterValue
Range:
0 - 999999999
*
100000
Function:
Enter the counter value to be used in the integrated
precise stop function, par. 1-83.
The maximum permissible frequency at
terminal 29 or 33 is 110 kHz.
1-85 Precise Stop Speed Compensation Delay
Range:
1-100 ms
*
10 ms
Function:
Enter the de lay time for sensors, PLCs, etc.
for use in par. 1-83 P r ecise Stop Function.
In speed compensated stop mode, the delay
time at different frequencies has a m ajor
influence on the stop function.
