Setting the Motor Maximum Speed
You can set the maximum speed of the Servomotor with the following parameter.
•
Rotary Servomotors
•
Linear Servomotors
You can achieve the following by lowering the maximum speed of the Servomotor.
•
If the motor speed exceeds the setting, an A.510 alarm (Overspeed) will occur.
•
With a Linear Servomotor, you can increase the upper limit for the setting of Pn281 (Encoder
Output Resolution). Refer to the following section for details.
7.5 Encoder Divided Pulse Output
Changing the setting of the parameter is effective in the following cases.
•
To protect the machine by stopping machine operation with an alarm when the set speed is
reached or exceeded
•
To limit the speed so that the load is not driven beyond the allowable moment of inertia
Refer to relevant manual from the following list for the relationship between the speed and the
allowable moment of inertia.
