YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
Description
When the drive is running and a there is a drive fault, operation will switch to Bypass
Mode. When you remove the fault, the operation will go back to Drive Mode
0 : Disabled
1 : Enabled
Sets the mode of bypass control at power-up.
0 : OFF-DRIVE
1 : AUTO-DRIVE
3 : AUTO-BYPASS
5 : Powerup HOA Memory
Enables and disables the function to auto transfer to EMOV bypass if the drive declares a
fault when the bypass is running in EMOV drive.
0 : Disabled
1 : Enabled
0 : Disabled
1 : Always Motor 1
2 : Always Motor 2
3 : Always Motor 1 AND 2
4 : OR in HAND and AUTO
5 : MOTOR 1 in HAND OR in AUTO
6 : MOTOR 2 in HAND OR in AUTO
7 : AND/OR in HAND and AUTO
8 : MOTOR 1 in HAND AND/OR in AUTO
9 : MOTOR 2 in HAND AND/OR in AUTO
10 : MOTOR 1,2 in HAND AND/OR in AUTO
Delays the drive or bypass Run from when commanded (after RUN, RUN ENABLE, and
RUN INTERLOCK are all asserted).
Lets the bypass run at a preset speed starting when it receives a Run command, and it
ignores the BAS Interlock Input. The drive frequency reference stays at this preset speed
until Z1-12 [Run Delay Time] is expired.
0 : Disabled
1 : Enable time delay only
Sets the frequency that the bypass uses when it delays the Run command.
When you enter a Run command, it asserts the damper actuator output. When you program
an input for Interlock and the time set to this parameter expires before the Interlock input
activates, it will trigger a fault.
Note:
Set this parameter to 0.0 s to disable this function.
When you enter a Run command, it asserts the damper actuator output. When you program
an input for Interlock and the time set to this parameter expires before the Interlock input
activates, it will trigger a fault.
0 : Disabled
1 : Frequency
2 : Frequency + Current
Note:
If the motor is running in reverse, Energy Savings will not function.
Sets the value of the drive frequency reference for use in comparison to enter or exit
Energy Savings Mode.
Lets the system switch when the output current is more than this level of motor rated
current for the time set in Z1-22, Energy Time.
Sets the tolerance around the drive frequency reference value during comparisons to enter
or exit Energy Savings Mode.
Note:
Units, default, and range are different for different o1-03 [Frequency Display Unit
Selection] values.
