Installing and Wiring the Drive

English

11

{FRS}

Coast to Stop

The motor voltage will be switched off immediately and the motor will
coast. This function can be programmed to operate in two different
modes via parameter b88 [FRS Select].

Note: The drive will start when 11 {FRS} input is removed without
reissuing a start command even if in 3-wire (momentary) control.

12

{EXT}

External Fault

When this input is active, an E12 fault indication will be issued (e.g. an
input received from thermal contacts). The fault indication will be
cleared with a reset 18 {RS}.

Important: After a reset 18{RS} command, the drive will start again if a

start command is active (00{FW}, 01{RV},or 20 {STA}).

13

{USP}

Unintentional
Start Protection
on Power Up

This function is designed to guard against unintended starting when
input power is removed and then restored. In this case, if a start/run
command is issued immediately upon/after power is restored an E13
fault will be issued. A new start command or a reset 18 {RS} command
will clear the fault indication.

15

{SFT}

Program Lock

Protects stored parameter values from being overwritten. See
parameter b31 [

] for the 4 different levels of

protection.
