Installation & Wiring

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

Pb88-[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
Pb31-[Program Lock Select] for the 4 different levels of protection.

16

{AT}

4-20mA Select

Activates input terminal OI for use as a 4-20mA input. If no
input terminal is programmed for this setting, the factory
default input is O (0-10V) and the output frequency will
correspond to the value of the inputs to the O and/or OI control
inputs.
Note:

PA01-[Frequency Command Select] determines from

what source the output frequency is commanded.
