605C Frequency Inverter
ANALOG OUTPUT
The analog output blocks converts the demand percentage into a form suitable for driving the
analog output electronics of the Inverter.
F
unctional Description
The Inverter has two analog outputs. There is an ANALOG OUTPUT function block associated
with each of these:
ANALOG OUTPUT 1 is associated with terminal 6
ANALOG OUTPUT 2 is associated with terminal 7
The scaling and offset parameters are applied to the demand value as shown.
If ABS is TRUE then the final output is the magnitude of value after being scaled and offset.
If ABS is FALSE then the final output will be limited to be within the range selected by TYPE.

Parameter Descriptions
VALUE
Range: -300.00 to 300.00 %
The demanded value to output.
SCALE
Range: -300.00 to 300.00 %
A scaling factor to apply to VALUE . A scaling factor of 100.00% has no effect.
OFFSET
Range: -300.00 to 300.00 %
An offset added to VALUE after the scaling factor has been applied. An offset factor of 0.00%
has no effect.
ABS
Range: FALSE / TRUE
When true the output sign is ignored.
TYPE
Range: Enumerated - see
below
The output hardware type, either Volts or Amps.
• ANALOG OUTPUT 1 does not support the -10..+10V type and if this type is selected then
the output will be forced to zero.
• ANALOG OUTPUT 2 does not support the current types and if these are selected then the
output will be forced to zero.
Warning: For correct operation, ensure that the hardware range selected using switch bank
SW2 corresponds to the TYPE selected. The values that this parameter may take are:
Enumerated Value : Type
0 : 0..+10 V
1 : 0..20 mA
2 : 4..20 mA
3 : -10..+10V
See below for how to set the I/O configuration switches.
