SERVO AMPLIFIERS
BASICS
Test Operation Mode
The operation of the servo amplifier and
servo motor can be checked before wiring
the signal wires.
앬
Test operation mode 1:
Operation without commands
The motor can be operated even without
speed/position commands, start signals,
or other external signals. This enables
users to test the servo alone, prior to the
fabrication of a control panel, and to con
-
firm the operation of the machine.
앬
Test operation mode 2:
Operation without a motor
The servo amplifiers can be checked with
-
out connecting them to a motor. This is
convenient when you want to confirm a
command or peripheral sequence before
operating the actual machine. You can
monitor the simulated rotation speed and
command status of the motor on the dis
-
play screen of the amplifier as you would
during normal operation.
Output signal forced output
Forcing output signals ON or OFF, such as
alarm and ready signals, makes it easy to
perform external wiring and sequence
checks.
Subtotal 76 different parameters can be
set. The basic parameters are listed below.
For parameters marked with an asterisk *,
turn the power OFF after setting and turn
the power back ON to complete the
setting.
