EXT-12: Usage of Pulse Input Signal – Sub-B
This function is to select the usage of encoder pulse
signal of ‘Sub-B’ board. The pulse signal from encoder
can be used as the motor speed feedback or frequency
reference.
[None]
The encoder pulse signal is not used.
[Feed-back]
The encoder pulse signal is used as the motor speed
feedback. The inverter can maintain the motor speed
constantly, regardless of the load fluctuation, by using
the encoder feedback. Set the encoder pulse method
and the number of pulse in EXT -15 and 16. Main speed
is set in DRV-04 [Frequency mode]. The encoder pulse
related functions must be set correctly for better
performance in EXT -15 ~ EXT-24.
Code LCD Display Setting in Feed back
EXT-12 F mode Feed-back
EXT-15 F pulse set A+B
EXT-16 F pulse num 360 ~ 4096
EXT-22 PG P-gain 0 ~ 30000
EXT-23 PG I-gain 0 ~ 30000
EXT-24 PG Slip Freq 0 ~ 200[%]
EXT-25 ASR P-Gain 10 ~ 500[%]
EXT-26 ASR I-Gain 10 ~ 9999[mSec]
EXT-27 Trq + Limit 0 ~ 200[%]
EXT-28 Trq – Limit 0 ~ 200[%]
[Reference]
The encoder pulse signal is used as the frequency
reference. When this function is selected, the frequency
reference selected in DRV-04 is ignored. Reference
Frequency versus Pulse Input Curve can be made by
four parameters of EXT -18 ~ EXT-21.
