Test Without A Motor - YASKAWA SGD7S-1R9D Product Manual

Test without a Motor

A test without a motor is used to check the operation of the host controller and peripheral
devices by simulating the operation of the Servomotor in the SERVOPACK, i.e., without actually
operating a Servomotor. This test allows you to check wiring, debug the system, and verify
parameters to shorten the time required for setup work and to prevent damage to the machine
that may result from possible malfunctions. The operation of the motor can be checked with
this test regardless of whether the motor is actually connected or not.

Motor Information and Encoder Information
The motor and encoder information is used during tests without a motor. The source of the
information depends on the device connection status.

7.6 Convenient Function to Use during Trial Operation
Simulates operation
without a motor.
Meaning
Source of Information
Information in the motor that is connected
• Setting of Pn000 = n.X (Rotary/Linear Startup
Selection When Encoder Is Not Connected)
• Rated motor speed and maximum motor speed
The values previously saved in the SERVOPACK will
be used for the rated motor speed and maximum
motor speed.
Use the monitor displays (Un020: Rated Motor
Speed and Un021: Maximum Motor Speed) to check
the values.
• Encoder resolution: Setting of Pn00C = n.X
(Encoder Resolution for Tests without a Motor)
• Encoder type: Setting of Pn00C = n.X (Encoder
Type Selection for Tests without a Motor)
Source of Information
Information in the external encoder that is con-
nected
• Resolution: 256
• Encoder type: Incremental encoder
