H2: Multi-Function Digital Outputs - YASKAWA Z1000 Technical Manual

Setting 14: Fault Reset
When the drive detects a fault condition, the fault output contact closes, the drive output shuts off, and the motor coasts to
stop (specific stopping methods can be selected for some faults such as L1-04 for motor overheat). After removing the Run
command, clear the fault either by pressing the RESET key on the HOA keypad or closing a digital input configured as a Fault
Reset (H1-oo = 14).
Note: Remove the Run command prior to resetting a fault. Fault Reset commands are ignored while the Run command is present.
Setting 19: PI Disable
Close a digital input to indefinitely disable the PI function. When the input is released, the drive resumes PI operation.

Setting 24: External Fault
The External fault command stops the drive when problems occur with external devices.
To use the External fault command, set one of the multi-function digital inputs to 24. The HOA keypad will display EFo
where o is the number of the terminal to which the external fault signal is assigned.
For example, if an external fault signal is input to terminal DI-3, "EF3" will be displayed.
The conditions of setting 24 are:
• Terminal status is normally open
• Detection condition is always detected
• Stopping method is coast to stop.
Setting 60: Motor Pre-Heat 1
A DC current can be circulated through the motor windings to create heat and prevent moisture from condensing on the wire.
Motor Pre-Heating can only be initiated by closing a digital input programmed as a Motor Pre-Heat input (H1-oo = 60). The
level of the DC current used by the Motor Pre-Heat function is determined by b2-09
<1> Details on this function can be found in the standard Z1000 Programming Manual (SIEPC71061645) at
www.yaskawa.com.
A Run input will be given priority over a Motor Pre-Heat input and when the Run command is removed, the motor pre-heating
will resume if the Motor Pre-Heat input is still closed.
