PU-E Series Pickup Installation

The PU-E series pickup is an economical way to monitor motor speed. Its patented design provides for
ease of installation in otherwise diffi cult to reach areas. The PU-E operates from a +5V power supply,
producing a 5 volt square wave whose frequency is proportional to speed. This signal is fed into the
MDP control as a speed or position reference for the microprocessor.

-1 Option Wiring

The -1 option board is a module which allows external up and down push buttons to be wired to the
unit. These buttons operate exactly like the Up and Down buttons on the user interface. This module
is commonly used to allow PLCs or hand-held pendants to operate the front-panel remotely. Wire for
the external buttons are attached via a 3mm European terminal block on the -1 option board. The
buttons are activated by shorting the terminal labeled Com to either the Up or Down terminal.

Basic Operating Instructions

Control Algorithm Discussion

The MDP series controls are based on a pulse-accumulation algorithm. The advantage to this type of
algorithm is that it allows the control to follow a master process with exceptional long-term accuracy.
The MD10P and MD3P controls have three parameters which allow the user to adjust how aggressively
the units drive the motor to achieve the target speed. These 3 parameters are as follows:

P Gain - This is the proportional gain for the control loop. In pure pulse-accumulation algorithms, there
is no loop error to base a 'P' factor on; therefore, these units must estimate error based on several
control loop factors. Those who are familiar with PID control tuning should be aware that the MD10P
and MD3P control's P Gain is somewhat different than that of standard velocity-form PID algorithms.
The P Gain is a function of instantaneous error, a measure of the difference between the target (desired)
speed and the current speed of the motor.

I Gain -This is the integral gain for the control loop. The I Gain is a function of accumulated error, a
measure of the difference between the target (desired) speed and the current speed of the motor.

Pulse Accumulation Limit - This parameter allows the user to limit the maximum number of pulses
the drive will accumulate prior to intentionally losing count and therefore long-term accuracy. See the
details for parameter 29 in the Parameter Description section.

Pulse-Accumulation Loop PI Tuning

Many applications do not require tuning of the P and I Gain parameters beyond the supplied factory
default settings. If more responsiveness is desired or if the motor oscillates an unacceptable amount when
changing speeds, it may be necessary to adjust the P and I gains to obtain optimal performance.

Increasing the P and/or I gains will cause the control to drive the motor more aggressively. Decreasing
the P and/or I gains will cause the control to perform more sluggishly. Properly tuning the P and I
gains encompasses more than independently adjusting the P and I. The ratio between the two is
very important as well. Although initial tuning can be a time-consuming task, here is a basic outline
of how to proceed:

10

Test Procedure: Adjust the target (displayed) speed as expected during normal operation, including
testing inhibit and jog transitions if applicable.

Tuning Method:

Step 1 - Connect control to loaded motor with application's anticipated load for realistic

tuning

Step 2 - Perform test procedure

Step 3 - If control performs adequately, stop tuning and record settings

Step 4 - If control is too sluggish or takes too long to reach the target speed, then try

increasing I Gain slightly (add 250). Perform the test procedure again. Continue

increasing I Gain until motor starts to slightly oscillate or become unstable. At this

point, decrease the I Gain by 250.

Step 5 - If control is too aggressive or is causing the motor to oscillate or become unstable,

then try decreasing I Gain slightly (subtract 250). Perform the test procedure again.

Continue decreasing I Gain until motor starts to stabilize and regulate more accurately.

Step 6 - Once I is set, adjust P Gain and perform test procedure. In this control, additional P

Gain may or may not improve response or stability. Experimentation will be required.

Accel and decel settings have a small impact on PI tuning as well. Specifi cally, when accel and decel
settings are extremely fast, they can cause the control loop to perform more sluggishly. Another thing
to keep in mind is that PI tuning also affects accel and decel times. For instance, a sluggishly tuned PI
control loop may take longer than the programmed accel and decel times to reach the target; whereas,
an aggressively tuned PI control loop will reach the target faster.

Master (Rate and Time) and Follower (Ratio) Modes Explained

The MDP controls have two basic modes of operation, master and follower. In the Master modes, the
controls are capable of operating independently; whereas, in the Follower Mode, the control requires a
signal from a master to operate. The Follower Mode is used in applications which require the MDP to
closely follow a master process. For example, if a factory has ten conveyors which must be synchronized
over long periods of time, an industrial engineer could use one MDP as a master control for the fi rst
conveyor and nine MDPs as slaves or followers which would receive their speed commands from the
fi rst conveyor's master control or pickup.

In Master Rate Mode, the MDP controls the rate of the motor by tracking the motor's pickup pulses
which are applied to signal input 1 (S1). In this mode, the display indicates in rate units such as
Gallons-per-minute, feet-per-second, and RPM.

In Master Time Mode, the MDP controls the process time by tracking the motor's pickup pulses which
are applied to signal input 1 (S1). In this mode, the display indicates in time units such as HH:MM or
MM:SS, where HH is hours, MM is minutes, and SS is seconds. This mode is most-commonly used
in time-sensitive processes such as conveyor ovens and plating applications.

In Follower Mode, the MDP tracks the number of pulses which are applied to the master signal input
(S2). From these pulses, it calculates the rate of the master process. This rate is then multiplied by
the percentage which is displayed on the user interface. The display is in 0.1% of master units. For
example, 675 = 67.5 percent of master speed. A master running at 1350 RPM, would cause the
follower to run its motor at 67.5% * 1350 RPM or 911.25 RPM. Typical follower applications include
synchronized rotation, synchronized conveyors, and some web-material processes.

Operating the User Interface (The Long Story)

Although the MDP user interface is very versatile, it is also simple to setup and operate. With just
a few button presses, it allows the user to confi gure a number of adjustable parameters. The LED
display has three basic operating modes: Running Mode, Parameter-Selection Mode, and Value Mode.
Each of the three modes have specifi c visual indicators that allow the user to immediately determine
the current state or mode of the user interface. Parameter-Selection Mode and Value Mode can

only be entered if the Program Enable jumper is in the “On” position.

Running Mode is the default display of the unit when power is applied. The MDP will spend the majority
of its time in this mode. In Running Mode, the display shows the target value in the appropriate user­defi ned format of rate, time, or percentage. The control will continuously attempt to drive the motor at
the requested target rate. In this display mode, the Up and Down buttons increase or decrease the
displayed target value until either the display minimum or display maximum limit is reached. Depending
on the alarm confi guration, these buttons may also serve as an alarm-silence or alarm-reset button.
Example displays for rate, time, and follower operating modes are 13.60, 45:30, and 1000.

12

Parameter-Selection Mode can be entered by simply pressing and holding the Enter button down for
three seconds. Once in Parameter-Selection Mode, the far left of the display will be a ‘P’. The right side

of the display will indicate the currently selected parameter number for editing purposes. Pressing the
Up or Down button will increase or decrease the selected parameter number on the display. Although
the parameter numbers are in numerical order, some numbers are skipped. These numbers represent
reserved parameters that are not yet implemented and are not displayed. Once the desired parameter
number is displayed, a press of the Enter button will change the display to the Value Mode. When

in Parameter-Selection Mode, pressing the Enter button with parameter 0 selected will cause
the unit to return to Running Mode. Example displays for Parameter-Selection Mode are P 1, P

13, and P 54. See the Software Parameters for a list of available parameters.

Value Mode is used to modify the value of the selected parameter. When in Value Mode, the two
dots which form the colon, between digits two and three, will alternately fl ash (one, then the other) to
inform the user that a parameter’s value is being edited. Pressing the Up or Down button increases or
decreases the selected parameter’s value. See the Software Parameters for a list of allowable values
and ranges. Value changes take effect immediately. For example, when scrolling through the alarm
output conditions, the relay will activate as the always-active selection is passed. Once the desired
value is showing in the display window, pressing the Enter button again will return to Parameter­Selection Mode. The new value is not saved in permanent memory until the Enter button is pressed.
Removing power from the unit while in Value Mode may result in the specifi ed new value being lost.

Parameter Descriptions

Parameter 0 – Exit to Running Mode

When parameter 0 is selected in Parameter-Selection Mode, the unit will return to Running
Mode and display the running value. This should be selected once changes to parameters are
completed.

Parameter 1 – Model Number (Read Only)

This is a number which represents the base model number for the product. The model codes
for the MD10P ,MD3P, and MD3E are 10 ,11, and 13 respectively.

Parameter 2 – Software Build (Read Only)

The software build is a code which identifi es the software version of the unit.

Parameter 3 – Hardware Version (Read Only)

The hardware version is a code which identifi es which hardware was used to build the unit.

Parameter 4 & 5 – Serial Number, Major & Minor (Read Only)

These parameters are reserved for future use as an electronic serial number and are unique
to each manufactured unit.

Parameter 10 – Operating Mode

This parameter defi nes the operating mode for the entire unit. There are two basic modes of
operation, master and follower. In master modes, the unit controls the load using either rate
or time units. In follower mode, the unit controls the load in percentage of master rate. The
following modes are available for the MDP:

Mode 1 – Master, Rate Mode

In Rate Mode, the MDP displays in user-defi ned rate units such as RPM, Gallons per
Hour, or Feet per Second. See applications for examples.

Mode 2 – Master, Time Mode

In Time Mode, the MDP displays in time units using the format AA:BB. By default AA:BB
represents minutes (AA) and seconds (BB). Optionally, it can be confi gured to represent
hours (AA) and minutes (BB) or other user-defi ned units with a 1:60 relationship. When
setting parameters which are confi gured in display units, the programmed value is the
determined by the formula (AA * 60) + BB. In HH:MM displays, this is the total number
of minutes. In MM:SS displays, this is the total number of seconds. See applications
for examples.

Mode 3 – Follower Mode

In Follower Mode, the MDP displays in percentage units, where 1000 equals 100.0 percent
of the master rate. For example, if the display indicates 985, 98.5, or 9.85, the MDP will
attempt to run at exactly 98.5 percent of the master rate. Display settings are always

Parameter 11 – Display Intensity

Parameter 13 – Decimal Point (DP) Position

entered ignoring the decimal point's position. See applications for more examples.

This parameter adjusts the intensity of the LED display digits in the front panel of the unit. The
values of 0 – 31 correspond to a gradual change from very dim to very bright. This is often useful
when the MDP is used in the same panel as other pieces of equipment with LED displays and
a uniform display brightness is desired. Simply adjust the MDP to match its surroundings.

This selects the format of the display with respect to the decimal point’s position. This parameter
does not effect the value entry for other parameters. For example, if the user desires to display

10.00 at 300RPM, then parameter 30 would be set to 1000, parameter 31 would be set to 300,
and parameter 13 would be set to 2.

Mode 0: Fixed XXXX
Mode 1: Fixed X.XXX
Mode 2: Fixed XX.XX
Mode 3: Fixed XXX.X
Mode 4: Fixed XXXX.

16

Parameter 14 – Keypad Mode

This parameter selects the operating mode of the front-panel push buttons. In some
applications, increasing or decreasing the scroll rate provides the user more controllability
when entering settings. Parameters 14 and 15 affect only the Up and Down buttons when
the user interface is in Running Mode. These settings also apply to remote Up / Down
buttons which are attached via the -1 option board.

Mode 1: Linear, Constant Rate

In linear mode, pressing and holding the Up or Down buttons will cause the display to
continuously change value in the requested direction until either the Display Minimum
or Display Maximum is reached. The displayed value will scroll at a constant rate which
is specifi ed using parameter 15.

Mode 2: Non-linear, Accelerating Rate

In non-linear mode, pressing and holding the Up or Down buttons will cause the
display to continuously change value in the requested direction until either the Display
Minimum or Display Maximum is reached. The displayed value will initially scroll at a
slow rate and increase in speed until the maximum scroll rate is achieved. The initial

Parameter 15 – Keypad Scroll Mode

Parameter 16 – S1 / S2 Input Edge & Prescaler Confi guration

scroll rate is specifi ed using parameter 15.

This parameter sets the scroll speed for the front-panel push buttons. The function of this
parameter varies slightly depending on the Keypad Mode. See parameter 14 for more
details.

This parameter determines how the MDP processes the S1 and S2 signal inputs. It specifi es
which signal edge is used for measurements and the value of the internal frequency dividers
or prescalers. Modes with prescalers greater than 1 should only be used if the input pulse
rate on S1 or S2 exceeds the unit's maximum native pulse rate (see specifi cations for details);
otherwise, the control loop may become sluggish and unnecessarily inaccurate. Use the
following chart to confi gure this parameter. As an example, assume an application requires
input pulse rates on S1 of 120,000 pulses-per-minute and S2 of 35,000 pulses-per-minute.
According to the electrical specifi cations, the unit can only accept 50,000 pulses-per-minute
on each the S1 and S2 inputs. With this in mind, the S1 and S2 prescalers should be selected
as Falling / 4 and Rising / 1, respectively. In this case, parameter 16 would be set to 2.

Parameter 18 – Power-up Mode

This parameter defi nes the mode which determines the default Running Value when power
is initially applied to the MDP.

Mode 1: Default to Zero

When in this mode, the unit will default to zero (display units).

Mode 2: Default to Power-Up Value

When in this mode, the unit will default to the Power-up Value, parameter 19.

Mode 3: Default to Previously Running Value

When in this mode, the unit will default to the previous running value before power
was removed. A previous running value must have been active for at least 3 seconds

to be recalled after power has been disconnected and reapplied.

17

Parameter 19 – Power-up Value

When Power-up Mode is set to 2, this parameter will designate the default display value at
power-up in display units.

Parameter 20 – Display Minimum

This parameter defi nes the lower end of the display range. This is the value which limits how
low the user is able to scroll the displayed value in Running Mode. In Rate and Time modes,
this value is set in display units. In Follower Mode, this is set in percentage of the master rate.
For example, in Follower Mode, 1250 represents 125.0 percent of the master rate.

Parameter 21 – Display Maximum

This parameter defi nes the upper end of the display range. This is the value which limits how
high the user is able to scroll the displayed value in Running Mode. In Rate and Time modes,
this value is set in display units. In Follower Mode, this is set in percentage of the master rate.
For example, in Follower Mode, 150 represents 15.0 percent of the master rate.

Parameter 23 – Acceleration Setting

This parameter determines how fast the MDP will accelerate toward the displayed target setting.
This parameter is set in display units of change per second such as RPM, GPM, or feet per
second. In Follower Mode, this parameter is set in RPM units.

Parameter 24 – Deceleration Setting

This parameter determines how fast the MDP will decelerate toward the displayed target setting.
This parameter is set in display units of change per second such as RPM, GPM, or feet per
second. In Follower Mode, this parameter is set in RPM units.

Parameter 26 – Proportional (P) Gain

The Proportional Gain is the fi rst of two parameters which defi ne the responsiveness of the
control with respect to how fast it responds to changing loads. Because the MDP controls
are pulse-accumulation drives, the P Gain responds differently than the same parameter in a
standard velocity-form PID control. The higher the P Gain, the more aggressively the unit will
drive the load. See the PI Control Tuning section of the manual for more details.

Parameter 27 – Integral (I) Gain

The Integral Gain is the second of two parameters which defi ne the responsiveness of the
control with respect to how fast it responds to changing loads. The higher the I Gain, the more
aggressively the unit will drive the load. When using high PPR pickups or encoders, it will be
necessary to decrease the I Gain to prevent unwanted oscillation and instabilities. See the PI
Control Tuning section of the manual for more details.

Parameter 29 – Pulse Accumulation Limit

This parameter sets the limit for the maximum number of pulses the drive will accumulate prior
to intentionally losing count and therefore long-term accuracy. Because the MDP controls are
pulse-accumulation drives, they are able to accurately track a master (in Follower Mode) pulse­by-pulse. That is, they are able to run for days, weeks, or months and remain completely in
sync with a master drive or process; unfortunately, this functionality comes at a small cost.

By default, if the main pickup signal were lost and then reattached, the unit may run at high
speeds for many seconds while attempting to make-up what would have been lost pulses.
Once it catches up, it returns to normal operation. In some applications, this is a nuisance. In
these cases, the Pulse Accumulation Limit, parameter 29, can be lowered to limit the maximum
number of pulses the drive will remember.

This parameter is set from 0 to 9999, where 0 is no accumulation and 9999 is maximum
accumulation. As this value approaches zero, the unit will gradually lose its ability to drive the
motor and eventually stop the motor completely. It may be necessary to increase the value of
this parameter for application which demand higher long-term accuracy.

18

Parameter 30 – Signal Input 1 (S1) Display Reference

This is the number to be displayed when at the user-specifi ed motor Reference RPM. In Rate
Mode, this value represents rate units such as feet, ounces, or revolutions. In Time Mode, this
value represents the reference time measured in seconds or minutes. If the desired display
is HH:MM, then all values should be entered in minutes. If MM:SS is desired, then all values
should be entered in seconds. In Follower Mode, this value is the percentage of the master rate
in 0.1% units. For example, 1000 equates to 100%. See applications for more examples.

Parameter 31 – Signal Input 1 (S1) Reference RPM

This is the reference RPM at which the Display Reference value should be displayed. In Rate
and Time Modes, this value represents the RPM of the encoder to which the Display Reference
corresponds. In Follower Modes, this value is not used. See applications for examples.

Parameter 32 – Signal Input 1 (S1) Pulses per Revolution

This is the number of pulses per revolution for the signal input 1 (S1). The MDP supports pickups
and encoders from 1 to 2048 pulses per revolution.

Parameter 33 – Signal Input 1 (S1) Deadband (Follower Mode Only)

When in Follower Mode, it is often desirable for the follower unit to continue to slowly make­up the small pickup pulse differential between the master and follower's position. In some
applications, it is not necessary for the follower to continue to slowly seek the master's exact
pulse position when the master rate is at zero. In these cases, the Deadband parameter can
be set above zero to force the MDP to stop driving the motor slowly and cause it to inhibit until
the master starts rotating again. At that point, the follower will automatically make-up the pulse
differential as it starts to rotate. The deadband is disabled by setting it to zero seconds.

Parameter 35 – Signal Input 2 (S2) Input Confi guration

This parameter determines the operating mode of signal input 2 (S2).

Mode 1: Disabled (Follower Mode)

The S2 input is inactive. This is the required setting for Follower Mode.

Mode 2: Emergency Stop 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 emergency-stop mode. While in this mode, the armature output will
immediately be turned off. Once the S2 input returns to an electrically low state or wired
to the unit's common, the output will become active.

Mode 3: Emergency Stop 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 emergency-stop mode. While in this mode, the armature output will immediately
be turned off. Once the S2 input returns to an electrically high (+5V) state or allowed to
fl oat disconnected, the output will become active.

Mode 4: Inhibit 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 inhibit mode. While inhibited, the armature output will decrease
according to the decel setting until zero output is reached. Once the S2 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 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 inhibit mode. While inhibited, the armature output will decrease according to
the decel setting until zero output is reached. Once the S2 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.

19

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

Parameter 36 – Signal Input 2 (S2) Setpoint

Parameter 37 – Signal Input 2 (S2) Pulses per Revolution

Parameter 38 - Front Panel DoubleClick Mode

Parameter 40 – User Input 1 (UIN1) Confi guration

master.

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.

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.

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.

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.

20

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 star t
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

Parameter 50 – Alarm 1 Conditions

stopped master.

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.

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.

21

Mode 5: Active When Display Value Outside Range

The alarm output will activate when the displayed value is less than the lower limit setting
or greater than upper limit setting.

Mode 6: Active When Target (Display) = Zero

The alarm output will activate when the displayed value is equal to zero. This allows the
alarm output to be used to drive a mechanical brake to decrease stopping time or to
provide holding torque at zero speed.

Mode 7: Active When Main Pickup Signal (S1) Stalled or stopped

The alarm output will activate when the main pickup signal input (S1) has stalled or
stopped. The alarm lower limit (Parameter 57) is used to specify the stall timeout, in
seconds, under a motor stall condition. When using the lower limit to set the stall timeout,
an inhibit command or zero speed command will not be recognized as a stall condition.
The pickup is considered to have stalled if the timeout passes with no pickup pulses when
the target (displayed) value is greater than zero and the control has not been given an
inhibit command. The alarm upper limit (Parameter 58) is used to specify a zero speed or
stopped timeout condition in seconds. When using the upper limit to set a zero speed or
stopped timeout, an inhibit command, a zero speed command or a motor stall condition
will all be recognized as a stopped condition. The pickup is considered to have stopped
after the timeout passes with no pickup pulses.

Note: When using the upper limit to set a stopped timeout the lower limit should
be set to zero.

Mode 8: Active When Driving At Maximum Conduction Angle

The alarm output will activate when the control is driving the motor at the maximum
conduction angle. This can be used to determine if the control is running away due to a

broken pickup signal wire when stall-detection is not desired.

This setting confi gures the output mode and reset method for the alarm 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 52 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 52 for reset details. The pulsed modes are commonly used for audible alarms
where a constant output would be considered distracting or awkward.

This setting determines which actions will cause an active alarm to be silenced or reset.

Mode 1: No Silencing, Reset On Any Button Press

In this mode, an active alarm cannot be silenced. Once the alarm condition ceases to
exist, however, any user-interface button may be pressed to cause a manual reset.

Mode 2: No Silencing, Reset On S2 Input High (Not Wired To Common)

Similar to Mode 1. Once the alarm condition ceases to exist, setting the S2 input to a
high (+5V) state or allowing it to fl oat disconnected will cause a manual reset.

Mode 3: No Silencing, Reset On S2 Input Low (Wired To Common)

Similar to Mode 1. Once the alarm condition ceases to exist, setting the S2 input to a
low (COM) state or wiring it to common will cause a manual reset.

22

Mode 4: Silencing Enabled, Reset On Any Button Press

When the conditions for an active alarm persist, pressing any user-interface button will
result in the alarm being silenced or deactivated, but not reset. A second attempt to reset
the alarm must be made after the condition cease to exist to clear the alarm.

Mode 5: Silencing Enabled, Reset On S2 Input High (Not Wired To Common)

Similar to Mode 4. Setting the S2 input to a high (+5V) state or allowing it to fl oat
disconnected will cause the alarm to be silenced or reset depending on the current state
of the alarm conditions.

Mode 6: Silencing Enabled, Reset On S2 Input Low (Wired To Common)

Similar to Mode 4. Setting the S2 input to a low (COM) state or wiring it to common
will cause the alarm to be silenced or reset depending on the current state of the alarm

conditions.

This will cause the display to fl ash when an alarm condition is active.

This parameter defi nes the number of seconds the output should be enabled during the ‘on’
phase of an active pulsing alarm’s output.

This parameter defi nes the number of seconds the output should be disabled during the ‘off’
phase of an active pulsing alarm’s output.

This setting determines how many pulses are output when the alarm is activated and is confi gured
in pulse output style. When 0 is entered, the unit will be set for continuous pulses while the

alarm is active.

This setting defi nes either the lower limit, the lower end of a range for the alarm region or a stall
timeout. Alarm limits are set in display units without regard to decimal point or colon position.
In Rate and Follower Modes, a limit of 123 could represent a display value of 123, 12.3, 1.23, or

0.123. When in Time Mode, a limit of 123 would represent 1:23 on the display. When the lower
limit is being used to set a stall timeout for parameter 50 mode 7, the setting is in seconds.

This setting defi nes either the upper limit, the upper end of a range for the alarm region or a stop
timeout. Alarm limits are set in display units without regard to decimal point or colon position.
In Rate and Follower Modes, a limit of 123 could represent a display value of 123, 12.3, 1.23, or

0.123. When in Time Mode, a limit of 123 would represent 1:23 on the display. When the upper
limit is being used to set a stop timeout for parameter 50 mode 7, the setting is in seconds.

When set to a value of 5, the unit will be reset to factory default settings. This can also be
achieved by applying power to the unit with both the Enter and Down buttons depressed. The

programming jumper must be in the "On" position for this method to function.

When set to a value of 5, the unit will store all adjustable parameters to the user default area.
The user default area is intended to be a location where an OEM or integrator can store settings
specifi c to their application. Using this, an OEM can easily refresh their custom settings in the
fi eld if an end-user accidentally reconfi gures the unit unsuccessfully. Another common use for
this area is testing and initial setup. The user can store known-good settings here and easily
experiment without the fear of losing the optimal confi guration.

When set to a value of 1, the unit will restore the all adjustable parameters from the user default
area. See parameter 98 for additional information.

Editing and increasing the display intensity parameter should cause the display digits to
become brighter.

Review routing of power wires in machine to minimize electrical noise. Look for other
devices which share the same circuit which may be producing unacceptable levels of
line noise. In some applications, such as welding equipment, a careful regiment of
applying an AC line filter, re-routine wires, dividing circuits, using shielded cable, and
properly grounding devices will usually solve the problem.

The unit is designed to operate with AC lines from 48-62 Hertz (cycles per second).
This is typically not a problem because the international standards are 50 and 60 Hertz.

Alarm output parameters not configured properly
Review alarm output parameters. The alarm relay output can be tested by selecting

the “Always On” value for the Activation Condition parameters for the alarm output.
When doing this, the relay click should be audible and the NC (Normally Closed) and C
(Common) terminals should become internally shorted at the terminal block.
