· Cold start: The motor protection operation time responds to an overload situation which
is suddenly reached when strating a stationary motor.
· Hot start: The motor protection operation time responds to an overload situation which
occurs when the motor was running continuousely at its rated current.

P2 Momentary Power Loss
P2-00 Momentary Power Loss Operation Selection
Selects the drive operation when a momentary power loss occurs (the main circuit DC voltage
falls below the P2-03 level). The drive can automatically return to the operation it was
performing before the power loss.
Momentary Power Loss Operation Selection
0 : Disabled (Default)
When the power supply falls below the P2-03 (Uv Detection Level) value for 10ms, a Uv
(Undervoltage) fault will be triggered to shut off the drive output and the motor coasts to stop.
1 : Recover if CPU Has Power
When the CPU of the drive is powered after a momentary power loss, the drive will resume the
operation. The KEB function will not perform even if KEB is enabled.
P2-01 Minimum Baseblock (bb) Time
Sets the minimum baseblock time when power is restored right after a momentary power loss.
