12 : DRIVE TRIPPED
Logic 1 when the drive has tripped and the display shows the fault code.
13 : STO STATUS
Logic 1 when both STO inputs are present and the drive is able to be operated
1404
RELAY OUTPUT
HYSTERESIS CONTROL
This parameter works in conjunction with parameter 1501 ANALOG OUTPUT 1 FUNCTION
SELECT and 1507 ANALOG OUTPUT 2 FUNCTION SELECT = 2 or 3 to set a band around the
target speed (1501 = 2) or zero speed (1501 = 3). When the speed is within this band, the
drive is considered to be at target speed or Zero speed.
This function is used to prevent “chatter” on the relay output if the operating speed
coincides with the level at which the digital / relay output changes state. e.g. if parameter
1507 ANALOG OUTPUT 2 FUNCTION SELECT = 3, 2008 MAXIMUM FREQUENCY/SPEED LIMIT =
50Hz and parameter 1404 = 5%, the relay contacts close above 2.5Hz

ANALOG OUTPUT 1
(TERMINAL 8) FUNCTION
SELECT
Selects the type of output signal information indicated from terminal 8.
Note :
When using settings 0 – 7 the output is a digital format (Logic 1 = 24V).
When using settings 8– 11 the output is an analog format.
Note : When using settings 4 – 7, parameters 3203 ADJUSTABLE THRESHOLD 1 UPPER LIMIT
and 3202 ADJUSTABLE THRESHOLD 1 LOWER LIMIT must be used together to control the
behaviour. The output will switch to Logic 1 when the selected signal exceeds the value
programmed in parameters 3203 ADJUSTABLE THRESHOLD 1 UPPER LIMIT, and return to
Logic 0 when the signal falls below the value programmed in 3202 ADJUSTABLE THRESHOLD
1 LOWER LIMIT.

2 : AT TARGET FREQUENCY
(SPEED).
Logic 1 when the output frequency matches the setpoint frequency
3 : OUTPUT FREQUENCY

LIMIT
Logic 1 when the motor torque exceeds the adjustable limit. (See note above)
7 : ANALOG INPUT 2
SIGNAL LEVEL >= LIMIT.
Logic 1 when the signal applied to the Analog Input 2 exceeds the adjustable limit. (See note
above)
