(velocity monitor).
Load: less than 2 mA. Output resistance: 1 KΩ.
Positive voltage at forward revolution
Monitor 2 MON2 16 (14) Type 9 0.5V±20%/rated current (current monitor).
Load: Less than 2 mA. Output resistance: 1 KΩ.
Positive voltage when forward revolution power is
output.
Start ready completes 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).
Encoder channel C

COP 11 (13) Type 7 Output by the open collector (the logic can be reversed
using the Func5 bit 6 parameter).

Type 6 Alarm code output and alarm bit output (ALM1) are
switched by Func2 bit 6 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.
Positioning complete INP 39 (24)
(25)
Type 6 This signal indicates that the contents of the deviation
counter have come within the setting range.

is selected with entry of ±2 V (standard
setting). In order to enable velocity addition, Func1 bit
7 must be set at 1.
*1 The pin numbers in parentheses denote the ground or common side of each signal.
*2 For the circuit type, see Fig. 9-16.
The output contents depend on the Func4 parameter setting.
