YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
Description
Sets the motor overload protection with electronic thermal protectors.
0 : Disabled
1 : Variable Torque
Note:
When you connect only one motor to a drive, set L1-01 = 1 [Variable Torque].
External thermal relays are not necessary in these conditions.
Sets the operation time for the electronic thermal protector of the drive to prevent damage
to the motor. Usually it is not necessary to change this setting.
Sets drive operation when the PTC input signal entered into the drive is at the oH3 [Motor
Overheat Alarm] detection level.
0 : Ramp to Stop
1 : Coast to Stop
2 : Fast Stop (Use C1-09)
3 : Alarm Only
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)
Sets the primary delay time constant for the PTC input signal entered to the drive. This
parameter prevents accidental motor overheat faults.
Sets the reference current for the motor 1 thermal overload detection. When the current
level > 0.0 A, you cannot set this value < 10% of drive rated current.
Sets the function that keeps the current electronic thermal protector value after power loss.
0 : Disabled
1 : Enabled
2 : Enabled, using RTC
Description
Sets the drive operation after a momentary power loss.
0 : Disabled
1 : Enabled for L2-02 Time
2 : Enabled while CPU Power Active
Sets the maximum time that the drive will wait until it tries to restart after power loss.
Sets the minimum time to continue the drive output block (baseblock) after a baseblock.
Sets the time for the drive output voltage to go back to the correct voltage after it
completes speed searches.
Sets the voltage at which the drive triggers a Uv1 [DC Bus Undervoltage] fault. Usually it
is not necessary to change this setting.
