9.3 Frequency Ratio Settings
When using two sensors with different number of impulses, or in case of mechanical
gear transmission ratio between both encoders, the higher one of the two frequencies
must be adjusted to the lower one by corresponding setting of the scaling factors.
Accurately calculated values are better than experimental results.
No. Parameter Remark
019 „Multiplier 1“ Proportional factor for sensor 1
For SMC1.3, this parameter must be set to value 1!
020 „Divisor 1“ Reciprocal factor for Sensor 1
For SMC1.3, this parameter must be set to value 1!
031 „Multiplier 2“ Proportional factor for sensor 2
For SMC1.3, this parameter must be set to the value 1!
032 „Divisor 2“ Reciprocal factor for Sensor 2
For SMC1.3, this parameter must be set to value 1!
In this example,
the frequency 2
is greater than
frequency 1 by a
factor of 2.
For adjustment,
parameter
"Divisor 2" can
be set to 2.
By this scaling
procedure of
frequency 2,
internally both
calculated
frequencies are
approximately
equal and the
calculated
frequency ratio is
close to 0.
