Yaskawa Z1000U HVAC Matrix Bypass - Manual (Page 217)

Setting 0: Unused (Available for Serial Comms)
Note: Multiple digital input terminals can be programmed for “Unused (Available for Serial Comms)” (Z2-0o = 0). The drive will run only when
all digital inputs programmed for “0” are active. This feature applies to settings 0 and 22. All other selections should only be set once in
parameters Z2-01 to Z2-08.
Setting 3: DRV Multi-Function Input S3 (H1-03 Setting)
Refer to H1-03 to H1-08: Functions for Terminals S3 to S8 on page 165 for available H1-03 multi-function input settings.
Setting 4: DRV Multi-Function Input S4 (H1-04 Setting)
Refer to H1-03 to H1-08: Functions for Terminals S3 to S8 on page 165 for available H1-04 multi-function input settings.
Setting 5: DRV Multi-Function Input S5 (H1-05 Setting)
Refer to H1-03 to H1-08: Functions for Terminals S3 to S8 on page 165 for available H1-05 multi-function input settings.
Setting 6:DRV Multi-Function Input S6 (H1-06 Setting)
Refer to H1-03 to H1-08: Functions for Terminals S3 to S8 on page 165 for available H1-06 multi-function input settings.
Setting 7: DRV Multi-Function Input S7 (H1-07 Setting)
Refer to H1-03 to H1-08: Functions for Terminals S3 to S8 on page 165 for available H1-07 multi-function input settings.
Setting 8: DRV Multi-Function Input S8 (H1-08 Setting)
Refer to H1-03 to H1-08: Functions for Terminals S3 to S8 on page 165 for available H1-08 multi-function input settings.
Setting 21: Run (AUTO Mode)
Starts and stops the bypass when Z1-08 is set to 1.
Setting 22: Run Enable (Safety)
Stops the drive from running regardless of Z1-08 setting. Z2-31 controls the message displayed on the HOA keypad when this
input is open.
Note: Multiple digital input terminals can be programmed for “Run Enable (Safety)” (Z2-0o = 22). The drive will run only when all digital inputs
programmed for “22” are active. This feature applies to settings 0 and 22. All other selections should only be set once in parameters Z2-01
to Z2-08.
Setting 23: Run Interlock (BAS)
Stops the drive and triggers alarm AL02. Use parameters Z1-13 and Z1-15 to modify Interlock settings.
Setting 24: Remote Transfer to Bypass
Stops the drive and turns on the bypass when a Run command is issued while in Drive Mode. The fault for this mode is
controlled by parameter Z1-05. Parameter Z1-40 controls the length of time that the drive must be faulted before switching to
Bypass Mode.
Setting 25: Smoke Purge Bypass Run to Destruction
Stops the drive, turns on the bypass, and triggers alarm AL03. The bypass runs continuously regardless of any faults or alarms.
Setting 26: Smoke Purge Drive Run to Destruction at Smoke Purge Preset Speed
Bypass controller will stay in this state even if the drive faults or is unavailable. The preset speed is equal to the value set to
Z1-10.
Setting 27: Motor OR Select
2-Motor OR function; 0/1 for Motor 1/2. Behavior defined by Z1-11.
Setting 28: Motor AND Select
2-Motor AND function; 0/1 for 1/2 motor. If 1 motor, then look to Motor OR input for selected motor. Behavior defined by
Z1-11.
Setting 29: Motor 1 Overload Contact
When input is open, declare an oL Fault, issue an EF0 fault to the drive, delay per EF0 Fault Delay Time (Z1-30), and open
bypass (K3) contactors.
Setting 30: Motor 2 Overload Contact
When input is open, declare an oL Fault, issue an EF0 fault to the drive, delay per EF0 Fault Delay Time (Z1-30), and open
bypass (K3) contactors.
