Item
Parameter Name
Description
32
Frequency Generator Output Frequency
This sets the output frequency from the frequency generator.
Example: Set Item 32 to 7200 PPM and the square wave output frequency is
7200/60 equals 120Hz.
33
Frequency Generator MIN
This sets the lowest output frequency from the frequency generator. Note: if
you are using mode 1 of Item 30 of the
GSDA-CM-8
then this Item is controlled
by Item 42 of the
GSDA-CM-8
.
34
Frequency Generator MAX
This sets the highest output frequency from the frequency generator. Note: if
you are using mode 1 of Item 30 of the
GSDA-CM-8
then this Item is controlled
by Item 43 of the
GSDA-CM-8
.
Analog Input
40
Analog Input Destination Routing
This sets how the analog input is to be used in the GSD8 drive.
• Mode 0: Off
This will cause the input to not be used.
• Mode 1: Target Speed
This will allow the analog input to control the set speed of the GSD8 drive.
• Mode 2: Percent of Target
This will control a percentage of the set speed of the GSD8 drive.
• Mode 3: RESERVED
• Mode 4: Frequency Generator Rate
This will control the frequency output of the frequency generator. Note:
When using this mode Item 30 of the serial communications board must be
set to a mode of 1.
• Mode 5: Main Tach Signal
This can be used as a main tach signal from the GSD8 controlled motor
instead of using a standard pickup on S1 of the GSD8 drive.
• Mode 6: Leader Tach Signal
This can be used as a master tach signal instead of a standard pickup on S2
of the GSD8 drive.
41
Analog Input Source Type
This identifies what type of input signal is being used.
• Mode 1: Potentiometer
• Mode 2: 0 to +5 VDC (Voltage)
• Mode 3: 4 to 20 mA (Current)
42
Minimum NUMERIC Value Sent Out by
Analog Input
This sets the numeric value which will be created when the analog input is
at its lowest voltage (or lowest current for 4-20 mA input source type). Note:
if you are using mode 1 of Item 30 of the
GSDA-CM-8
then this controls the
Frequency Min.
43
Maximum NUMERIC Value Sent Out by
Analog Input
This sets the numeric value which will be created when the analog input is at
its highest voltage (or highest current for 4-20 mA input source type). Note:
if you are using mode 1 of Item 30 of the
GSDA-CM-8
then this controls the
Frequency Max.
