5.3 Description of Function Codes 5.3.2 E codes (Extension terminal functions)
Select speed control parameter 1, 2 “MPRM1”, “MPRM2” assignment (Function code data = 78, 79)
The combination of the ON/OFF states of digital input signals “MPRM1” and “MPRM2” selects one of 4 different
level speed control parameter sets. These parameters are valid under vector control with speed sensor, V/f control
with speed sensor, and sensorless vector control.
( Function codes d01 to d08)
Speed control constant 1: d01 to d06
Speed control constant 2: A43 to A50
Speed control constant 3: b43 to b50
Speed control constant 4: r43 to r50
Cancel customizable logic “CLC” assignment (Function code data = 80), Clear all customizable logic
timers “CLTC” assignment (Function code data = 81)
Terminal command “CLC” stops the operation of customizable logic. Terminal command “CLTC” clears all
customizable logic timers.
( Function code U codes)
Cancel anti-regenerative control “AR-CCL” assignment (Function code data = 82)
Anti-regenerative control can be canceled with “AR-CCL”. When “AR-CCL” is ON, the H69 setting is ignored, and
anti-regenerative control is disabled.
( Function code H69)
PG input switching “PG-SEL” assignment (Function code data = 83)
The PG option card command/feedback channel can be changed with “PG-SEL”. Switching is possible only while
the inverter is stopped. If terminal operation is performed while the inverter is running, it will stop before switching.
This function cannot be used with synchronous motor drive with sensor.
• If using a dual system PG option card.
• If using a single system PG option card
( Function code F01)
Usage example
If switching between two motors with encoder, an external switching circuit is installed for both the motor and
encoder, but with dual system PG option cards, the encoder switching circuit will not be necessary if using this
function.
