User Input #1 (UIN1) Setup Parameters
40
User Input 1 (UIN1) Configuration
This Parameter determines the operating mode of user input 1 (UIN1).
• Mode 1: Disabled
The UIN1 input is inactive.
• Mode 2: Emergency Stop When UIN1 High (Not Wired To Common)
When the UIN1 input is at an electrically high (+5V) state or allowed to float
disconnected, the GSDA-DP-D will enter emergency-stop mode. While in
this mode, the armature output will immediately be turned off. Once the
UIN1 input returns to an electrically low state or wired to the unit’s common,
the output will become active.
• Mode 3: Emergency Stop When UIN1 Low (Wired To Common)
When the UIN1 input is at an electrically low state or wired to the unit’s
common, the GSDA-DP-D will enter emergency-stop mode. While in
this mode, the armature output will immediately be turned off. Once the
UIN1 input returns to an electrically high (+5V) state or allowed to float
disconnected, the output will become active.
• Mode 4: Inhibit When UIN1 High (Not Wired To Common)
When the UIN1 input is at an electrically high (+5V) state or allowed to float
disconnected, the GSDA-DP-D will enter inhibit mode. While inhibited,
the armature output will decrease according to the decel setting until zero
output is reached. Once the UIN1 input returns to an electrically low state
or is wired to the unit’s common, the output will start to accelerate toward
the previous running value.
• Mode 5: Inhibit When UIN1 Low (Wired To Common)
When the UIN1 input is at an electrically low state or wired to the unit’s
common, the GSDA-DP-D will enter inhibit mode. While inhibited, the
armature output will decrease according to the decel setting until zero
output is reached. Once the UIN1 input returns to an electrically high (+5V)
state or allowed to float disconnected, the output will start to accelerate
toward the previous running value.
• Mode 6: (JOG2) Jog When UIN1 High (Not Wired To Common)
When the UIN1 input is at an electrically high (+5V) state or allowed to float
disconnected, the GSDA-DP-D will enter JOG2 mode. While in JOG2 mode,
the display will immediately change to the programmed JOG2 setpoint,
Parameter 41. The unit will start accelerating or decelerating toward the
JOG2 setting at the configured accel and decel rates. Once the UIN1 input
returns to an electrically low state or is wired to the unit’s common, the
output will start to accelerate or decelerate toward the previous running
value. In Follower Mode, the unit will operate as its own master. This allows
an application to jog by overriding a stopped master.
• Mode 7: (JOG2) Jog When UIN1 Low (Wired To Common)
When the UIN1 input is at an electrically low state or wired to the unit’s
common, the GSDA-DP-D will enter JOG2 mode. While in JOG2 mode,
the display will immediately change to the programmed JOG2 setpoint,
Parameter 41. The unit will start accelerating or decelerating toward the
JOG2 setting at the configured accel and decel rates. Once the UIN1 input
returns to an electrically high (+5V) state or allowed to float disconnected,
the output will start to accelerate or decelerate toward the previous running
value. In Follower Mode, the unit will operate as its own master. This allows
an application to jog by overriding a stopped master.
41
User Input 1 (UIN1) Setpoint for
JOG2 Function
When the UIN1 configuration, Parameter 40, is set to one of the JOG2 modes,
this Parameter defines the JOG2 setpoint in engineering units. If the GSDA-
DP-D operating mode is set to Follower Mode, then this Parameter is set in
RPM units. This allows a follower control to be jogged when the master is
stopped.
