⑩ Selection of Motor Speed Control Voltage / DC+10V Signal Method
CAUTION
Set the Motor Speed Control Voltage so that it does not exceed the maximum rotation speed for the
spindle in use.
・ Set the parameter to
model E2530 CONTROLLER.
・ The Fig. 34 are Characteristics of the Motor Speed Control Voltage Signal and rotation speed by parameter
set to . The Fig. 35 are Characteristics of the Motor Speed Control Voltage Signal and rotation speed
by parameter set to
* VR = VR1or VR2
* Unit of rotational speed : 1,000min
* Rotation Speed(x10,000min
* VR = VR1or VR2
* Unit of rotational speed : 1,000min
* Rotation Speed(x1,000min
