Parameter Name
Description
42
Inhibit Configuration
This Parameter determines the accel/decel profile of the GSDA-DP-D when it is
going into and out of “Inhibit” Mode. There are 4 possible settings:
• Mode 0: No Accel/Decel
When going into Inhibit, the GSDA-DP-D will immediately shut off its
output, disregarding any Decel setting, and when coming out of Inhibit, the
GSDA-DP-D will immediately return to its Target Speed, disregarding any
Accel setting. This is exactly like the “E-Stop” behavior.
• Mode 1: Decel Only, No Accel
When going into Inhibit, the GSDA-DP-D will Decel to a stop using the
setting in Parameter 24, but when coming out of Inhibit, the GSDA-DP-D will
immediately return to its Target Speed, disregarding any Accel setting.
• Mode 2: Accel Only, No Decel
When going into Inhibit, the GSDA-DP-D will immediately shut off its
output, disregarding any Decel setting, but when coming out of Inhibit, the
GSDA-DP-D will Accelerate to its Target Speed, using the Accel setting in
Parameter 23.
• Mode 3: Use Both Accel and Decel
When going into Inhibit, the GSDA-DP-D will Decel to a stop using the
setting in Parameter 24, and when coming out of Inhibit, the GSDA-DP-D
will Accelerate to its Target Speed, using the Accel setting in Parameter 23.
Alarm Output #1 Setup Parameters
50
Alarm 1 Logical “OR” Activation
Conditions (Flags Table 1)
This Parameter, in conjunction with Parameters 51 & 52, defines which
conditions will result in the Alarm 1 output being activated. The function is
that of a Logical “OR”ing of the selected Drive Condition Flags. A setting of
zero defeats this “OR” function entirely. Please see the sections “Setting and
Reading Softswitches” and “Setting Alarm Conditions” for further details.
51
Alarm 1 Logical Activation Condition
Inverters (Flags Table 1)
This Parameter, in conjunction with Parameters 50 & 52, defines which
conditions will result in the Alarm 1 output being activated. The function
allows selected Drive Condition Flags to be “inverted” before being presented
to the “inputs” of the “AND” function (see Parameter 52). Please see the
sections “Setting and Reading Softswitches” and “Setting Alarm Conditions”
for further details.
52
Alarm 1 Logical “AND” Activation
Conditions (Flags Table 1)
This Parameter, in conjunction with Parameters 50 & 51, defines which
conditions will result in the Alarm 1 output being activated. The function is
that of a Logical “AND”ing of the selected Drive Condition Flags. A setting of
zero defeats this “AND” function entirely. Please see the sections “Setting and
Reading Softswitches” and “Setting Alarm Conditions” for further details.
53
Alarm 1 Output Style & Reset
Configuration
This setting configures the output mode and reset method for the Alarm 1
output.
• Mode 1: Constant & Auto Reset
In this mode, the alarm output will remain active until the alarm condition
ceases to exist. The alarm will automatically reset when the conditions
return to normal.
• Mode 2: Constant & Manual Reset
In this mode, the alarm output will remain active until the alarm is reset
manually. See Parameter 54 for details.
• Mode 3: Pulse & Auto Reset
In this mode, the alarm output will pulse on and off until the alarm condition
ceases to exist. The pulsed modes are commonly used for audible alarms
where a constant output would be considered distracting or awkward. The
alarm will automatically reset when the conditions return to normal.
• Mode 4: Pulse & Manual Reset
In this mode, the alarm output will pulse on and off until the alarm is
reset manually. See Parameter 54 for reset details. The pulsed modes
are commonly used for audible alarms where a constant output would be
considered distracting or awkward.
