4-3 Functions When Multi-function Feedback Option Board (3G3AX-PG01) Is Used Master Inverter AP, BP AN, BN EG5 EAP, EBP EAN, EBN 4 Functions Main motor M M Sub motor EC EC •For the Inverter (master Inverter) on the main motor side, you can select either the speed control or pulse train position control mode. •For the Inverter (slave Inverter) on the sub motor side, you need to select the pulse train position control mode. •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 (P019) : 01 (REF) Electronic gear ratio numerator (P020) : 3000 Electronic gear ratio denominator (P021) : 1024 Ч 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.) 4-123 Slave Inverter SAP, SBP SAN, SBN EG5 EAP, EBP EAN, EBN Electronic gear setting position selection (P019) REF (Position command side) REF (Position command side) FB (Position feedback side) FB (Position feedback side) Electronic gear ratio numerator (P020) 1024 2048 1024 2048 Electronic gear ratio denominator (P021) 2048 1024 2048 1024 Slave rpm/Master rpm 1/2 2 2 1/2
