Cascading factor
The cascading factor directly influences the set-value at the input Dig_In_1 (X5).
Encoder adaptation (C025 = -1-) under C026, C027 and C028.
The following constants can be adjusted under C026:
8192 incr./rev.
4096 incr./rev.
2048 incr./rev.
1024 incr./rev.
512 incr./rev.
Cascading constants, which cannot be represented as a power of two, can be
assigned under C027 / C028. The following relation applies:
Setting range of the factors:
( C027 from -3.2767 to +3.2767
( C028 from +0.0001 to +3.2767.
The quotient is limited to max. –32767.
Note!
For the largest possible internal resolution, set C026 = -0- (8192 incr./rev.) and
under C027 the value +0.8192 (8192 incr./rev. divided by 10,000) should be set.
Indicate the effective encoder constant, which is evaluated with the divisor
10,000, under C028.
Example:
Encoder = 4000 incr./rev.
C026 = - 0 -
C027 = 0.8192
C028 = 0.4000
Set-value conditioning of the slave
The value read from Dig_In_1, evaluated with C026, C027 and C028, forms the
set-value (speed and phase) for the internal control and is also the output value
at the digital frequency output.
The set-value for the corresponding drive can be evaluated by the gearbox factor
C032 and C033.
The direction of the slave can be changed with the CW/CCW changeover. If the
direction of rotation is changed while the machine is running, pulse losses, which
