differen-
tial phase (A and B phases) signal (set via parameter). Pulse width: See note.
Deviation counter reset TTL, line driver input with photoisolation, input current: 6 mA at 3 V
Sequence input 24-VDC, 5-mA photocoupler input, external power supply: 24
±
1 VDC, 50 mA min.
Output
signals Position feedback output A-, B-, Z-phase line driver output (EIA RS-422A)
A-phase and B-phase (dividing rate setting): 16 to 2,048 pulses/revolution
Z-phase: 1 pulse/revolution
Speed monitor output 0.5 V/1,000 r/min
Current monitor output 0.5 V/100%
Sequence output Alarm output, motor rotation detection, brake interlock, positioning completion;
open collector outputs: 30 VDC, 50 mA (except for alarm code output, which is 30
VDC, 20 mA)
External regeneration processing Required for regeneration of more than 30 times the motor’s ro-
tor inertia. Required for
regeneration
of more than
20 times the
motor’s rotor
inertia.
Protective functions Overcurrent, grounding, overload, overvoltage, overspeeding, runaway protection,
transmission errors, encoder errors, deviation counter overflow
Note The input pulse width must be meet the following conditions.

N Main circuit DC
output These are the connection terminals for the Regeneration Unit
(R88A-RG08UA). Connect these when the regeneration energy is high.

phase output Red
These are the terminals for outputs to the Servomotor.
V Servomotor V-
phase output White
W Servomotor W-
phase output Blue
Frame ground Green This is the connection terminal. Use a 100
Ω
or less (class-3) or bet-
ter ground. It is used in common for Servomotor output and power
supply input.
