SEPCIFICATIONS

Starting and Stopping Time

The motor starting time (tr) and stopping time (tf) under a constant load are calculated using the following formulas. Motor viscous torque and friction torque are ignored.

NM: Motor speed (min-1)

JM: Motor rotor moment of inertia (kgxm2 )

JL: Load converted to shaft moment of inertia (kgxm2)

TPM: Instantaneous peak motor torque when combined with a SERVOPACK (Nxm)

TL: Load torque (Nxm)

Load Moment of Inertia

The size of the allowable load moment of inertia of a servomotor depends on the capacity, and is limited to 5 to 30 times the motor inertia. This value is provided strictly as a guideline and results may vary depending on servomotor drive conditions. An overvoltage alarm is likely to occur during deceleration if the load moment of inertia exceeds the allowable load moment of inertia. SERVOPACKs with a built-in regenerative resistor may generate a regeneration overload alarm. Take one of the following steps if this occurs.

Reduce the torque limit.

• Reduce the deceleration rate.

• Reduce the maximum motor speed.

• Install an externally mounted regenerative resistor if the alarm cannot be cleared. Contact your Yaskawa Application Engineering Department.

Regenerative resistors are not built into 200 V for 50 W to 400 W and 100 V for 50 W to 400 W SERVOPACKs. The following figures show the tentative relationship between the load moment of inertia and motor speed using an example with a load moment of inertia 10 to 30 times the load moment of inertia at the motor shaft. External regenerative resistors are required when this condition is exceeded or if the allowable loss capacity (W) of the built-in regenerative resistor is exceeded due to regenerative drive conditions when a regenerative resistor is already built in.
