2.8 L: Protection Functions
YASKAWA ELECTRIC TOEP C710687 03B FSDrive-MV1000 Parameter Guide 205
n L2-05: Undervoltage Detection Level (Uv)
Determines the voltage at which a Uv1 fault is triggered or at which the KEB function is activated. This setting rarely
needs to be changed.
n
L2-40: Power Supply Overvoltage Operation Selection
Sets the operation when overvoltage is detected at the power supply side.
Setting 0: Ramp to Stop (uses the deceleration time set for C1-02)
Setting 1: Coast to stop
Setting 2: Fast Stop (uses the Fast Stop time set for C1-09)
Setting 3: Alarm only
n L2-41: Power Supply Overvoltage Detection Level
Sets the level at which overvoltage is detected at the power supply side as a percentage of the value set for o2-11
(Reference Voltage for Input Voltage Detection) in 0.1% units.
n
L2-42: Power Supply Overvoltage Detection Time
Sets the time before overvoltage at the power supply side (IOV) is detected, in 0.01 s units. If the state in which the
output voltage exceeds the value set for L2-41 continues for the time set for L2-42 or longer, overvoltage at the power
supply side (IOV) is detected.
n
L2-43: Inrush Current Suppression Circuit Selection
Selects if the inrush current suppression circuit (option) is used. Make sure to set the value to 1 when using the inrush
current suppression circuit.
0: Not used
1: Used
Note: 1. Make sure to set the value to 1 when using the inrush current suppression circuit.
2. This parameter is available from the software versions S0109 and later.
n L2-45: On-Delay Time of Inrush Current Suppression Circuit Breaker
Sets a delay time to output the close command for the inrush current suppression circuit breaker after the breaker is
closed. There is normally no need to change this parameter from the default value.
No.
<1> For details on the default settings, refer to Defaults by Drive Model Selection (o2-04) on page 87.
