Oscillator mode via inputs/outputs
In oscillator mode, the two movement frequencies f
H
and f
L
can be set
via the front panel and activated by the input FH/FL.
Available for units:
– without interface in OPT.1,
if P00 = 1
Prerequisites:
–
Manual mode via inputs/outputs inactive.
–
Front panel operation inactive.
NOTE
The following parameters must have been set (see chapter 3.3.1):
– Oscillator mode with parameter P00 = 1
– Higher oscillator frequency f
H
with parameter P04
– Lower oscillator frequency f
L
with parameter P73
1.
Activate the AUTOM input.
ATTENTION
The lower oscillator frequency f
L
must be less than the starting limit
frequency f
AM
of the stepping motor; see stepping motor sales
documentation.
2.
Set the higher and lower oscillator frequency via input FH/FL.
Input high:
Accelerate to higher oscillator
frequency f
H
.
Input low:
Accelerate or decelerate to
lower oscillator frequency f
L
.
NOTE
The INV_DIR input can be used for inverting the motor’s sense of
rotation.
3.
Activate the START input.
→
The motor rotates at the set movement frequency.
4.
Deactivate the START input or activate the STOP input.
→
The motor stops.
NOTE
For accurate stopping at the desired position, the STOP input should be
used.
NOTE
The motor can be deenergized with the CURRENT_OFF signal. In this
state, it does not have any holding torque.
The CURRENT_OFF signal is always evaluated.
