(velocity monitor).
Load: less than 2 mA. Output resistance: 1 kΩ.
Positive voltage at foreword revolution
Monitor 2 MON2 16 (14) Type 9 0.5 V±20%/rated current (current monitor).
Load: Less than 2 mA. Output resistance: 1 kΩ.
Positive voltage when forward revolution power is
output.
Start ready complete SRDY 41 (24)
(25)
Type 6 When the "Servo ON signal" is ready to receive after
the DC power supply of the main circuit is turned on,
this comes on and goes low impedance.
Current limit status ILIM 40 (24)
(25)
Type 6 This signal comes on in current limit status and is
effective as a bump end input or a standard for
prevention against current saturation at
acceleration/deceleration.

Type 8 Output by the line driver (26LS31) after the encoder
pulse is divided. The signal is received by the line
receiver (26LS32).

Type 8 The absolute value signal is output in serial form
(9600 bps or 1 M/2 Mbps) by the line driver (26LS31).
The signal is received by the line receiver (26LS32).
Encoder channel C

COP 11 (13) Type 7 Output by the open collector (the logic can be reversed
using the Func5 bit6 parameter).

Type 6 Alarm code output and alarm bit output (ALM1) are
switched by Func2 bit6 of the remote operator.
The alarm bit signal turns off in an alarm status.
The alarm code outputs various alarms as 4-bit binary
codes.
Low velocity LTG 39 (24)

Type 6 When the motor speed becomes lower than the set
value, this signal goes to low impedance.

*1 The pin numbers in parentheses denote the ground or common side of each signal.
*2 For the circuit type, see Fig. 9-20.
The output contents depend on the Func4 parameter setting.
