Motor overheat protection operation selection (F-06):
Select whether motor overheat protection is enabled or not.
Using this function requires <TVPT66-Z> or <TVTH66-Z> and the motor temperature sensor.
When <F-06> is set to "ON," the inverter trips in the following conditions:
・
Motor temperature exceeds a setting of the Motor_protect_temperature <G-17>.

Protection relay (86A) operation selection upon power failure (F-07):
Select a protection relay (86A) operation when VF66B (DC motor drive) detects power failure.
・
When the protection relay (86A) operation selection upon power failure is set to protection relay inactive
(F-07 = oFF)
Even if VF66B (DC motor drive) detects power failure, a protection relay (86A) will not be activated. An
operation command (or JOG command, DC brake command) is only set to "OFF" after the power is
restored, and power failure is reset. When the Instantaneous power interruption restart (b-07) is set to "ON,"
after the power is restored, power failure is automatically reset to restart VF66B (DC motor drive).
・
When the protection relay (86A) operation selection upon power failure is set to protection relay active
(F-07 = on)
When VF66B (DC motor drive) detects power failure, the protection relay (86A) will be activated and VF66B
(DC motor drive) will trip. In this case, like other protection operations, you should perform protection reset
using reset terminals or the [STOP/RESET] key. Even when the Instantaneous power interruption restart
(b-07) is set to "ON," VF66B (DC motor drive) does not automatically restart.
Warning
[About instantaneous power interruption restart]
If the Instantaneous power interruption restart (b-07) is set to "ON," the motor automatically restarts when the
power is restored after instantaneous power interruption is detected. Therefore, do not come close to the motor
while instantaneous power interruption is being detected.
Otherwise, you may be injured.
