OMNUC G5-SERIES AC SERVOMOTOR AND SERVO DRIVE USER'S MANUAL
Name Function and interface
You can switch maximum 4 electronic
gear ratio numerators by combining with
electronic gear switching input 1
(GESEL1).
This signal forcibly sets the speed
command to 0.
Changes to enable (set value: 1 to 3)
according to the setting of Zero Speed
Designation Selection (Pn315).
Designates the motor rotation direction
for speed commands.
Changes to enable (set value: 1)
according to the setting of Speed
Command Direction Selection (Pn301).
This signal designates the motor rotation
direction for torque commands.
Changes to enable (set value: 1)
according to the setting of Torque
Command Direction Selection (Pn318).
This is an emergency stop input.
When input, this becomes an
emergency stop input error and thereby
stop the motor.
This signal switches between inertia
ratio 1 and inertia ratio 2.
Name Function and interface
Encoder signals (or external encoder
signals during fully-closed control) are
output according to the setting of
Encoder Dividing Numerator (Pn011).
This is the line-driver output (equivalent
to RS-422). The maximum output
frequency is 4 Mpps.
Phase Z is output for encoder signals (or
external encoder signals during fully-
closed control). This is the line-driver
output (equivalent to RS-422).
