Analog torque
limit OTLA CN20-12 To use this signal, set [Pr. Po11] to "_1_ _". When OTLA is enabled,
torque is limited in the full servo motor output torque range. Apply 0 V
to +10 V DC between OTLA and LG. C of the power supply to
OTLA. The maximum torque is generated at +10 V.

Analog
input
Analog override OVC CN20-2 To use this signal, set [Pr. Po11] to "_ _1_". The signal controls the
servo motor setting speed by applying -10 V to +10V DC to between
VC and LG. The percentage will be 0% with -10 V, 100% with 0 V, and
200% with +10 V to the servo motor setting speed.

CN10-13
CN10-14 Input 24 V DC (24 V DC ± 10% 800 mA) for I/O interface. The power
supply capacity changes depending on the number of I/O interface
points to be used.
For sink interface, c of 24 V DC external power supply.
For source interface, connect - of 24 V DC external power supply.

I/F common
DOCOMD
CN10-37 Common terminal of input signals such as SON, RES, and others of
the servo amplifier. This is separated from LG.
For sink interface, connect - of 24 V DC external power supply.
For source interface, c of 24 V DC external power supply.
15 V DC power
supply P15R CN20-13 This outputs 15 V DC to between P15R and LG. This is available as
the power for OTLA and OVC. Permissible current: 30 mA
-12 V DC power
supply N12R CN20-15 This outputs -12 V DC to between N12R and LG. This is available as
the power for VC.
However, the voltage varies within the range of -12 V to -15 V.
Permissible current: 30 mA
Control common LG CN20-1
CN20-9
CN20-11
This is a common terminal for OTLA, OVC, OMO1, OMO2, and P15R.
Pins are connected internally.
Shield SD CN10-50
