In position range
To set the range when the error count pulse is less than the value driver will take it as complete of
positioning the CN1-18 will be engaged.
Electronic Gear
Denominator
The common denominator of the 4 numerator.
Numerator
Available range: 0 ~ 32767
If the servo motor feedback encoder is 2500ppr (2500 x 4 pulse per revolution) and the Denominator
is set to 5000, the Numerator set to 10000. The controller command pulse will be 5000 pulses to run the
motor one revolution.
Command pulses to
run one revolution
=
2500 (Encoder pulse per
revolution) X 4
/
10000 (Numerator)
5000 (Denominator)
Numerator1
Under the position operation Mode, Numerator 1 will be selected as the numerator of the electronic
gear ratio when CN1-32 is connected with 24G.
Numerator2
Under the position operation Mode, Numerator 2 will be selected as the numerator of the electronic
gear ratio when CN1-33 is connected with 24G.
Numerator3
Under the position operation Mode, Numerator 3 will be selected as the numerator of the electronic
gear ratio when CN1-35 is connected with 24G.
Note:
1. When A+B pulse mode is selected as pulse command input, the pulse count of electronic gear
must multiply by 4.
2. When electronic gear ratio is set too large, the servo motor may caused jiggles, the adequate
acceleration and deceleration is required.
