Meaning
With the parameter "No sup-
ply voltage L+" you activate
the diagnostic interrupt of the
channel in the case of no
supply voltage L+.
With the parameter "Refer-
ence speed" you define the
reference value for the drive
velocity. The drive velocity is
defined as percentage value
of the reference speed in the
range from -200 % to
+200 %.
The parameter "Maximum
speed" is used to define the
required maximum speed for
your application.
The "Increments per revolu-
tion" is used to define the
number of increments per
revolution (also in microstep
mode), which is required by
the drive for a revolution.
Value range
Deactivated
Activated
Floating-point number:
1.0 bis 20,000.0 (rpm)
The supported value range depends
on:
the signal type selected under
•
"Operating mode"
the value defined under "Incre-
•
ments per revolution"
the value defined under "Refer-
•
ence speed"
The low limit of the value range is:
for the signal type "PTO (A, B
•
phase-shifted - quadruple)":
0.1 Hz * 60 s/min * 4) / Incre-
ments per revolution
for the non-quadruple PTO sig-
•
nal types: (0.1 Hz * 60 s/min) /
increments per revolution
The high limit of the value range is
the minimum of the value:
2 * reference speed
•
and of the value:
for the signal type "PTO (A, B
•
phase-shifted - quadruple)":
(100 000 Hz * 60 s/min * 4) / In-
crements per revolution
for the non-quadruple PTO sig-
