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.
• Rotary Servomotor
If you use fully-closed loop control, the external encoder information is also used.
• Linear Servomotors
Motor Connection
Status
Information That Is Used Source of Information
Connected
Motor information
• Rated motor speed
• Maximum motor speed
Information in the motor that is connected
Encoder information
• Encoder resolution
• Encoder type
Not connected
Motor information
• Rated motor speed
• Maximum motor speed
• Setting of Pn000 = n.X (Rotary/Linear Servo-
motor Startup Selection When Encoder Is Not Con-
nected)
• 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 motor displays (Un020: Rated Motor Speed
and Un021: Maximum Motor Speed) to check the
values.
