YASKAWA Z1000 CIMR-ZU*A Series Programming Manual page 79

When an input terminal programmed for 42 closes, the drive will operate in the selected direction. The drive will stop when
the input opens.
The input programmed for 43 selects the direction. If the input is open, forward direction is selected. If the input is closed,
reverse direction is selected.
Note: This function cannot be used simultaneously with settings 40 and 41.
Settings 44, 45, and 46: Offset Frequency 1, 2, 3
These inputs add offset frequencies d7-01, d7-02, and d7-03 to the frequency reference.
Frequency 1 to 3 on page 61
Setting 47: Node Setup
If the SI-S3 option card is connected, closing this terminal sets a node address for operation on a CANopen network.
Settings 49 and 4A: GF1 Error (N.O., N.C.)
These input functions will stop the drive when a GF1 error is detected when set together with F6-86 (GF1 Error Detection
Selection) and F6-87 (GF1 Error Operation Selection).
Setting 50: Motor Pre-Heat 2
Sets the DC preheat current as a percentage of motor rated current (E2-01).
79 details.
Setting 51: Sequence Timer Disable
Drive ignores sequence timers and runs normally (based on b1-02/b1-16 source).
Setting 52: Sequence Timer Cancel
The sequence timers are canceled.
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.
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.
Setting 61, 62: External Speed Search Command 1, 2
These input functions enable Speed Search even if parameter b3-01 = 0 (no Speed Search at start).
Activation on page 33 for details on how to use the input signals.
Search.
Note: Simultaneously assigning Speed Search 1 and Speed Search 2 to the input terminals will trigger an oPE03 error.
Setting 63: Field Weakening
Enabled in V/f Control. When this input is closed, Field Weakening is performed.
