Mode 6: Jog When S2 High (Not Wired To Common)
When the S2 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 36. The unit will start accelerating or decelerating
toward the jog setting at the confi gured accel and decel rates. Once the S2 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 S2 Low (Wired To Common)
When the S2 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 36. The unit will start accelerating or decelerating
toward the jog setting at the confi gured accel and decel rates. Once the S2 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 36 – Signal Input 2 (S2) Setpoint
When the S2 confi guration, parameter 35, 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 37 – Signal Input 2 (S2) Pulses per Revolution
This is the number of pulses per revolution for the signal input 2 (S2). The MDP supports pickups
and encoders from 1 to 2048 pulses per revolution.
Parameter 38 - Front Panel DoubleClick Mode
When set to a value of 1, the setting of Parameter 35 and/or Parameter 40, particularly Modes
4 and 5 (Inhibit), have no effect; instead, "clicking" the ENTER Button twice in rapid succession
("Double-Clicking") will TOGGLE the MD10P/3P in and out of "Inhibit" mode. When in DoubleClick
mode, the Motor will decelerate to a stop, and the Display will show 4 dashes
"----" DoubleClicking again will cause the motor to accelerate up to the Target speed/time, and
the Display to return to its normal condition. When set to a value of Zero, the Inhibit function
is controlled exclusively by the signal level on the S2 and/or UIN1 Input(s), and the setting of
Parameters 35 and/or 40, and the "DoubleClick" function will have no effect. Note also that
the DoubleClick Inhibit is only honored in "Run" mode.
Parameter 40 – User Input 1 (UIN1) Confi guration
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 fl oat disconnected,
the MDP 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 MDP
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 fl oat disconnected, the output will become active.
