When the servo motor runs with load, the allowable frequencies will change according to the changes of the load inertia and rotation speed. Use the following equation to calculate the allowable frequency.

Allowable frequency =	Allowable frequency when servo motor run without load	x	Rated s peed	2 times
	m + 1		Operating speed		mi n.

m = load/motor inertia ratio

The users can select the adequate regenerative resistors according to the allowable frequencies by referring to the table below:

6.6.4 Electromagnetic Brake

When the servo drive is operating, if the digital output BRKR is set to Off, it indicates the electromagnetic brake is disabled and motor is stop running and locked. If the digital output BRKR is set to ON, it indicates electromagnetic brake is enabled and motor can run freely.

There are two parameters that affect the electromagnetic brake. One is parameter P1-42 (MBT1) and the other is parameter P1-43 (MBT2). The users can use these two parameters to set the On and Off delay time of electromagnetic brake. The electromagnetic brake is usually used in perpendicular axis (Z- axis) direction to reduce the large energy generated from servo motor. Using electromagnetic brake can avoid the load may slip since there is no motor holding torque when power is off. Without using electromagnetic brake may reduce the life of servo motor. To avoid malfunction, the electromagnetic brake should be activated after servo system is off (Servo Off).
