Speed Related Parameters When a Direct-drive Motor is Connected
As the maximum speed of SGMCS servomotor is approximately 1/10 of standard
SGM H servomotor, the unit of parameter setting is changed to 1/10 of the
standard.
When a SGMCS servomotor is connected, the SERVOPACK changes the setting
unit automatically as shown in the following table.
Also, when a motor with a maximum speed is 500 rpm or less is connected, the
SERVOPACK changes the setting unit to 1/10 of the standard automatically.
Besides the parameter, the speed setting for the auxiliary function Fn003 "Zero-point
search mode" is fixed to 6 [rpm] when a direct-drive servomotor is connected.
Also, the analog monitor output units are changed as shown in the shaded areas in the
table below.
