Note) 1. Regenerative brake frequency represents 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 AC230V (at 200V of the main voltage).
If the supply voltage fluctuates, frequency is in inverse proportion to the square of (Running supply voltage/230)
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. If the effective torque is within the rated torque, there is no limit in generative brake.
3. Consult us or a dealer if the load moment of inertia exceeds the specified value.
4. Specified releasing time is obtained with the use of surge absorber for brake (Z15D151 by Ishizuka Electronic or equivalent).
( ) represents the actually measured value using a diode (200V, 1A or equivalent)

*When you lower the torque limit setup (Pr5E and 5F), running
range at high speed might be lowered as well.
