11. CHARACTERISTICS
11.2 Power supply equipment capacity and generated loss
(1) Amount of heat generated by the driver
Table 11.1 indicates drivers' power supply capacities and losses generated under rated load. For thermal
design of an enclosure, use the values in Table 11.1 in consideration for the worst operating conditions.
The actual amount of generated heat will be intermediate between values at rated torque and servo off
according to the duty used during operation. When the servo motor is run at less than the maximum speed,
the power supply capacity will be smaller than the value in the table, but the driver's generated heat will not
change.

Note 1. Note that the power supply capacity will vary according to the power supply impedance. This value is applicable when the
power factor improving AC reactor or power factor improving DC reactor is not used.
2. Heat generated during regeneration is not included in the driver-generated heat. To calculate heat generated by the
regenerative option, refer to section 12.2.
