Mode 4: Inhibit When UIN1 High (Not Wired To Common)
When the UIN1 input is at an electrically high (+5V) state or allowed to fl oat disconnected,
the MDP 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 MDP
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 fl oat disconnected, the output will start to accelerate toward
the previous running value.
Mode 6: Jog When UIN1 High (Not Wired To Common)
When the UIN1 input is at an electrically high (+5V) state or allowed to fl oat disconnected,
the MDP will enter jog mode. While in jog mode, the display will immediately change to
the programmed jog setpoint, parameter 41. The unit will start accelerating or decelerating
toward the jog setting at the confi gured 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: 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
MDP will enter jog mode. While in jog mode, the display will immediately change to the
programmed jog setpoint, parameter 41. The unit will start accelerating or decelerating
toward the jog setting at the confi gured accel and decel rates. Once the UIN1 input
returns to an electrically high (+5V) state or allowed to fl oat 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.
Parameter 41 – User Input 1 (UIN1) Setpoint
When the UIN1 confi guration, parameter 40, is set to one of the jog modes, this parameter
defi nes the jog setpoint in display units. If the MDP 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.
Parameter 50 – Alarm 1 Conditions
This defi nes which conditions will result in the alarm 1 output being activated.
Mode 0: Always Inactive
The alarm output will remain in an inactive state. In this state, the NC and C contacts
will be internally electrically connected.
Mode 1: Always Active (When Power Is Applied)
The alarm output will become active when the power is applied to the unit. In this state,
the NO and C contacts will be internally electrically connected.
Mode 2: Active When Display Value Above Limit
The alarm output will activate when the displayed value is above the upper limit setting,
parameter 58.
Mode 3: Active When Display Value Below Limit
The alarm output will activate when the displayed value is below the lower limit setting,
parameter 57.
Mode 4: Active When Display Value Inside Range
The alarm output will activate when the displayed value is greater than or equal to lower
limit settings and less than or equal to the upper limit setting.
