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.
When ‘Sub-B’ board is installed, FU2-40 must be set to
‘V/F’.
[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. The encoder pulse related functions
must be set correctly for better performance in EXT-15 ~
EXT-24.
[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-20.
[Reference Frequency vs. Pulse Input]
EXT-13: Real Motor Speed Direction
If EXT-12 is set to 1 Feed-back with SUB-B mounted,
motor rotation direction is displayed in this parameter.
EXT-14: Encoder Feedback Frequency
Read frequency regardless of control mode if SUB-B is
installed with EXT-12 set to Feed-back.
EXT-15: Pulse Input Signal Selection – Sub-B
This code sets the encoder pulse to use. [A+B] uses two
encoder signal lines of A and B, and [A] uses one encoder
signal line of A or B.
–[A+B] is used when encoder and mot
or rotation direction is opposite
.
