Chapter 4 Setup
4-3
4-2 Setting the initial parameters
The servo parameters must be set to start up the servo drive system.
The servo parameters are input from the CNC. The input method will differ according to the CNC, so
refer to the Instruction Manual provided with each CNC.
4-2-1 Servo specification parameters
The servo specification parameters are determined according to the machine specifications and servo
system specifications.

SV017 SPEC Servo specification
selection
This is a HEX setting parameter. Set this as follows according to the
servo specifications.
Set all bits other than those above to 0.
SV025 MTYP Motor/Detector type Set the motor type.
Refer to the standard parameter list for each motor for the settings.
SV036 PTYP Regenerative resistor type This is a HEX setting parameter.
