Function assignment of external
terminal and control
(3) Alarm output signal (ALM, ALM2 signal)
Inverter alarm occurrence
(output shutoff)
Alarm output signal(ALM)
Alarm output 2 signal(ALM2)
Reset signal(RES)
(4) Input MC shutoff signal (Y91 signal)
⋅ The Y91 signal is output at occurrence of an alarm attributable to the failure of the inverter circuit or an alarm
caused by a wiring mistake.
⋅ When using the Y91 signal, set "91 (positive logic)" or "191 (negative logic)" to any of Pr. 190 to Pr. 196 (output
terminal function selection) to assign the function to the output terminal.
⋅ The following table indicates the alarms that will output the Y91 signal. (Refer to page 229 for the alarm
description.)
No.
1 Inrush resistor overheat (E.IOH)
2 CPU error (E.CPU)
3 CPU error (E.E6)
4 CPU error (E.E7)
5 Parameter storage device alarm (E.PE)
6 Parameter storage device alarm (E.PE2)
7 24VDC power output short circuit (E.P24)
Operation panel power supply short circuit
8
RS-485 terminal power supply short circuit(E.CTE)
9 Output side earth (ground) fault overcurrent protection (E.GF)
10 Output phase failure protection (E.LF)
11 Internal circuit error (E.BE)

⋅ If the inverter comes to an alarm stop, the
ALM and ALM2 signals are output. (Refer to
page 229 for the alarm description.)
⋅ The ALM2 signal remains on during a reset
period after alarm occurrence.
⋅ When using the ALM2 signal, set "94 (positive
Time
logic)" or "194 (negative logic)" to any of Pr.
190 to Pr. 196 (output terminal function selection)
to assign the function to the output terminal.
⋅ The ALM signal is assigned to the A1B1C1
contact in the initial setting.
