Functions
Configuration Example
•Main motor : Number of encoder pulses = 1024
•Sub motor : Number of encoder pulses = 3000
•Main motor rpm:Sub motor rpm = 2:1
For operation under the above conditions, set the following data in the slave Inverter.
Pulse train mode selection (P013) : 00 (pulse with 90 phase difference)
Electronic gear setting position selection (P019) : 01 (REF)
Electronic gear ratio numerator (P020) : 3000
Electronic gear ratio denominator (P021) : 1024 × 2 = 2048
The following shows an example of the ratio of slave rpm to master rpm depending on the P019 to
P021 settings.
(Note that the same number of encoder pulses (1024 pulses) should be set on both Inverters.)
