Input signals
Encoder signal
PA
A-phase signal
input terminal
A-, B- and Z-phase signals are input from the encoder.
The jumper connector is factory-set to complimentary.
Thus, the encoder need not be connected to PAR, PBR
and PZR.

Output signals
Contact
A, B, C Alarm output
1 changeover contact output indicating that the output
has been stopped by the inverter protective function.
230VAC 0.3A, 30VDC 0.3A. Alarm: discontinuity across
B-C (continuity across A-C), normal: continuity across
B-C (discontinuity across A-C).
The terminal function varies with the output terminal
function selection (Pr. 195) setting.
Refer to page 152 for details.
