YASKAWA ELECTRIC SIEP YAIZ1B 01E YASKAWA AC Drive – Z1000 Bypass Technical Manual
Description
Selects the bypass serial communications parity.
0: No Parity
1: Even Parity
2: Odd Parity
Selects the action to take when a serial communications fault is detected.
0: Ignore. A serial communications loss will result in no action being taken.
1: Alarm only.
2: Fault with EF0. An EF0 will be sent to the drive. If running in Bypass mode,
the bypass contactor will NOT open and the motor will keep running.
3: Fault with EF0 and Open Contactors. An EF0 fault will be sent to the drive
and the bypass contactor (K3) will be opened.
4: Alarm and run at preset speed set in Z3-10. Display AL14 alarm on
Operator.
Sets the time allowed to elapse since receiving serial communications before
triggering a communications fault.
A setting of 0.0 will never time out.
Sets the time to delay a serial communications response to a serial
communications command.
BACnet only.
Sets the least significant word of 22-bit virtual address.
BACnet only.
Sets the most significant word of 22-bit virtual address.
When a serial communications fault is detected and Z3-05=4, the resulting
value will become the frequency reference.
Communication Fault Detection Selection
0: Disabled. Serial communications fault detection is completely disabled.
1: Enabled. Behavior defined by Z3-05.
Enables and disables control of the digital inputs over a network. Wiring to
the physical digital input is not required.
0: Disable
1: Enable
Determines whether to restore the frequency reference, bypass command, or
both upon the reapplication of power after losing power.
WARNING! Sudden Movement Hazard. Setting this parameter to 2 or
3 will allow the bypass unit to start before receiving a valid network
message. Clear all personnel from the drive, motor, and machine area
before reapplying power. Failure to comply could result in injury to
personnel.
0: Disable
1: Reference Only
2: Run/Stop Only
3: Ref & Run/Stop
