Electronic Thermal Time Characteristics; Momentary Power Loss Settings: L2-01 To L2-05; Momentary Power Loss Detection: L2-01; Momentary Power Loss Ridethru Time: L2-02 - YASKAWA VARISPEED-616G5 Instruction Manual

Electronic Thermal Time Characteristics

In this example, L1-02 is set to 1 minute, the motor is operating at 60 Hz, and general-purpose
motor characteristics (EI-02=0) are used.

Disabled. (An undervoltage fault is detected when there is a momentary power loss.)
Enabled. (Restarts if power is restored within the L2-02 time. An under-voltage fault is detected
1
for a longer power loss.)
Enabled during CPU operation. (Restarts if power is restored while the CPU is operating. An

undervoltage fault is not detected.)
This constant specifies the processing that is performed when a momentary power loss occurs.

When power loss ridethru is enabled (setting 1 or 2), operation will be restarted after a speed search

if the power is restored within the allowed time interval.
When power loss ridethru is disabled (setting 0), an undervoltage fault will be detected if power is in-

V class, 0.4 kW Inverter. (See page 8 - 47.)
This setting is valid only when constant L2-01 is set to 1. Set the power loss ridethru time in seconds.
