YASKAWA ELECTRIC SIEP C710617 19A YASKAWA AC Drive CR700 Technical Manual
Description
V/f CL-V/f OLV CLV AOLV
Selects the drive operation when the PTC input signal input into the
drive reaches the detection level of oH3 [Motor Overheat (PTC
Input)].
0 : Ramp to Stop
1 : Coast to Stop
2 : Fast Stop (Use C1-09)
3 : Alarm Only
V/f CL-V/f OLV CLV AOLV
Sets the drive operation when the PTC input signal to the drive is at
the oH4 [Motor Overheat Fault (PTC Input)] detection level.
0 : Ramp to Stop
1 : Coast to Stop
2 : Fast Stop (Use C1-09)
V/f CL-V/f OLV CLV AOLV
Sets the primary delay time constant for the PTC input signal
entered to the drive. This parameter prevents accidental motor
overheat faults.
V/f CL-V/f OLV CLV AOLV
Sets the current value used as the reference for detecting the motor
overload state regarding the motor 1 electronic thermal protector.
V/f CL-V/f OLV CLV AOLV
Sets the current value used as the reference for detecting the motor
overload state regarding the motor 2 electronic thermal protector.
V/f CL-V/f OLV CLV AOLV
value when the drive stops receiving power.
0 : Disabled
1 : Enabled
Description
V/f CL-V/f OLV CLV AOLV
Sets the minimum baseblock time when power is restored.
V/f CL-V/f OLV CLV AOLV
Determines the voltage at which a Uv1 [DC Bus Undervoltage] fault is
triggered. Usually it is not necessary to change this setting.
Description
V/f CL-V/f OLV CLV AOLV
Sets the method of the Stall Prevention During Acceleration function.
0 : Disabled
1 : Enabled
2 : Intelligent (Ignore Decel Ramp)
3 : Current Limit Method
V/f CL-V/f OLV CLV AOLV
Sets the output current level used when the Stall Prevention function is
enabled during acceleration, as a percentage of the drive rated output
current.
V/f CL-V/f OLV CLV AOLV
Sets the lower limit for the stall prevention level during acceleration used
for constant output ranges as a percentage of the drive rated output current.
