Z1-19 Energy Savings Mode Frequency Reference Deadband
<1> Values are given in Hz, but actual values are dependent upon unit settings using drive parameters o1-03, o1-09, o1-10, and o1-11.
n
Z1-20: Energy Savings Mode Output Frequency Deadband
Sets the tolerance around the drive output frequency value during comparisons to enter or exit Energy Savings mode.
No.
Z1-20 Energy Savings Mode Output Frequency Deadband
<1> Values are given in Hz, but actual values are dependent upon unit settings using drive parameters o1-03, o1-09, o1-10, and o1-11.
n Z1-21: Energy Savings Mode Output Current Deadband
Sets the tolerance around the drive output current value during comparisons to enter or exit Energy Savings mode as a
percentage of motor rated current.
No.
Z1-21 Energy Savings Mode Output Current Deadband
n
Z1-22: Energy Savings Mode Time
Sets the time that the drive frequency reference and drive output frequency must be within the set limits before transferring
to Energy Savings mode.
No.
Z1-22
n Z1-23: Energy Savings Mode Frequency Reference Increase
Sets the value to add to the drive Frequency Reference when starting the transfer to bypass mode the drive when entering the
Energy Savings Mode.
No.
Z1-23 Energy Savings Mode Frequency Reference Increase
<1> Values are given in Hz, but actual values are dependent upon unit settings using drive parameters o1-03, o1-09, o1-10, and o1-11.
n
Z1-24: Contactor Open Delay Time
Sets the time to delay after commanding the drive output contactor K2 or bypass contactor K3 or 2-Motor AND/OR contactors
K4 and K5 to open to allow the contacts to open.
No.
Z1-24
n Z1-25: Contactor Close Delay Time
Sets the time to delay after commanding the drive output contactor K2 or bypass contactor K3 or 2-Motor AND/OR contactors
K4 and K5 to open to allow the contacts to close.
No.
Z1-25
n Z1-27 to Z1-29: Control Voltage Protection
The Bypass controller monitors the voltage to the contactor coils and the Bypass controller power supply. The controller will
detect brownout and blackout conditions. Blackout and brownout conditions will trigger an FB08 or FB09 fault and de-energize
the contactor coils.
n Z1-27: Phase Loss Brownout Voltage Level
Sets the brownout condition voltage level.
No.
