Settin s and O set Fre uency 1 2
These inputs add offset frequencies d7-01, d7-02, and d7-03 to the frequency reference.
Frequency 1 to 3 on page 63
Settin 7 Node Setup
If the SI-S3 option card is connected, closing this terminal sets a node address for operation on a CANopen network.
Settin s and A 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

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-
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.
