Chapter 5 Function Code
Terminal function assignment and data setting
Assignment of multi-frequency selection SS1, SS2, SS4, and SS8 (Function code data = 0, 1, 2, and 3)
16-stage speed operation is possible by turning on/off SS1, SS2, SS4, and SS8 signals.
(
Function code C05 to C19)
Assignment of accelerate/decelerate select RT1 and RT2 (Function code data = 4 and 5)
Accelerate/decelerate time 1 to 4 (F07, F08, and E10 to E15) can be switched by RT1 and RT2 signals.
(
Function code F07, F08)
Assignment of Self-hold select HLD (Function code data = 6)
This function can be used as the self-hold signal in the 3-wire operation by FWD, REV, HLD signals.
(
Function code F02)
Assignment of coast-to-stop order BX (Function code data = 7)
With BX ON, this function immediately block the inverter output. Motor becomes coast-to-stop (no alarm
indication).
Assignment of alarm (error) reset RST (Function code data = 8)
Turning RST from OFF to ON cancels bulk alarm output ALM. Turning it off erases the alarm display and
clears the alarm hold state. When turning RST on, keep it on for 10 ms or longer. This command should be
kept off during the normal operation.
Fig. 5.4-45
Assignment of external alarm THR (Function code data = 9)
Turning THR off immediately block the inverter output (so that the motor coasts to a stop), displays the alarm
0h2
, and outputs the bulk alarm ALM. This signal is self-held inside and is canceled by alarm reset.
Use the external alarm function when immediate block down of the inverter output is necessary
while peripheral equipment is in abnormal situation.
