1. About Regenerative brake frequency
the frequency of the motor's stops from the rated speed with deceleration without load.
. If the load is connected, frequency will be defines as 1/(m+1), where m=load moment of inertia/rotor moment of inertia.
・ When the motor speed exceeds the rated speed, regenerative brake frequency is in inverse proportion to the square of (running speed/rated speed).
・Power supply voltage is AC115 V(at 100 V of the main voltage)、AC230 V(at 200 V of the main voltage).
 If the supply voltage fluctuates, frequency is in inverse proportion to the square of (Running supply voltage) relative to the value in the table.
・When regeneration occurs continuously such cases as running speed frequently changes or vertical feeding, consult us or a dealer.
2. About unlimited regenerative brake frequency
If the effective torque is within the rated torque, there is no limit in generative brake.
3. About recommended moment of inertia ratio of the load and the rotor
Consult us or a dealer if the load moment of inertia exceeds the specified value.
