Notes: 1. The indicated control torque size is the short-term average torque (which changes with motor loss) when decelerated at maximum rate from 60Hz when the motor
is operated alone. It is not continuous regenerative torque. Deceleration from frequencies in excess of the base frequency will have lower average deceleration
torque values. The inverters have no built-in brake resistors, so when the regenerative energy is high, use the optional brake resistor. A BU model brake unit may
also be used (except with 0.1K and 0.2K models). The control torque when a brake resistor is used is shown on page 41; the same for when a brake unit is used
is shown on page 36.
2. Temperature to which units can be exposed for a short time, such as during transportation.
3. When an insufficient voltage or instantaneous power failure occurs, error display and output do not work, but the inverter is protected. Depending on the operating
status (e.g., the size of the load),. Overcurrent protection, regenerative overvoltage protection etc. may engage upon restoration of power.
4. This function is not available for the CC-Link Series.
5. For the CC-Link series, can be set by means of CC-Link communications or the optional parameter unit.
6. For the CC-Link series, can be set by means of CC-Link communications or one of the input terminals.
7. For the CC-Link series, display is possible when the optional parameter unit is in use.
8. This form is not available with the frequency setting volume type.
