4-3 Functions When Multi-function Feedback Option Board (3G3AX-PG01) Is Used 4-3 Functions When Multi-function Feedback Option Board (3G3AX-PG01) Is Used Functions That Need 3G3AX-PG01 •Generally, the Feedback Option Board (3G3AX-PG01) is required for the following two cases: • "05" (V2: sensor vector control) is selected in V/f characteristics selection A044. • "Pulse train frequency input" is selected in any of the following parameters: •"06" (pulse train frequency) is selected in frequency reference selection A001.
•With "10" (operation function result) selected in frequency reference selection A001, "05" (pulse train frequency) is selected in operation frequency input A setting (A141) or operation frequency input B setting (A142). •"03" (pulse train frequency) is selected in PID feedback selection A076. •When running the Inverter with V/f characteristics selection A044 set to "00" (VC), you can check the rotation direction with real frequency monitor d008.
(If positive frequency is detected when the forward command is activated, or if negative frequency is detected when the reverse command is activated, the rotation direction is judged as being normal.) 4 Functions V2 Control Mode Selection •Select a control method in V2 mode selection P012. •When "00" (ASR) is selected in P012, speed control mode is enabled. Select a frequency reference in frequency reference selection A001. •When "01" (APR) is selected in P012, the Inverter enables position control by generating frequency reference based on the position command pulse input from the pulse train position command input terminal, and on the position feedback detected by the encoder.
•Select any of the three pulse train position command input modes in pulse train mode selection P013. •To perform pulse train position control, allocate "48" (STAT) to any of the multi-function output terminals. While the STAT terminal is tuned on, pulse train position command input is accepted. •Position deviation can be cleared through external input. Allocate "47" (PCLR) to any of the multi- function output terminals. Tuning on and then off the PCLR terminal can clear position deviation data. •Allocate "22" (DSE) to any of the multi-function output terminals to enable excessive speed deviation signal output. •Set a deviation level in speed deviation error detection level P027.
When the deviation between real frequency and reference frequency exceeds the P027 set value, the DSE signal turns on. 4-116 Related functions A044, A001, A076, A141, A142
