PROGRAMMABLE FUNCTIONS
MODES
Master
Follower
SCALING
Pulses per Revolution Feedback (PPR FB) ranges from 1 to 59999
Maximum RPM Feedback (MAX RPM FB) ranges from 1 to 59999
Display Decimal Point (DSP DP) ranges from 0 to 0.00000
Maximum Display Units (DSP UNIT) ranges from 1 to 99999
*Pulses per Revolution Lead (PPR LD) ranges from 1 to 59999
*Maximum RPM Lead (MAX RPM LD) ranges from 1 to 59999
*These parameters are available in Follower Mode only.
Note: Values may be programmed in the range listed, provided that the
maximum equivalent frequency does not exceed 20971 Hz. If this occurs,
“OVFLW” will flash and a new entry will be required.
SETPOINTS
2 SPEED (Master Mode) - ranges from 0 to 99999 (or Display Unit Max.).
2 RAMP RATE (Master Mode) - ranges from 1 to 99999.
2 RATIO (Follower Mode) - ranges from 0.0000 to 1.9999.
2 RAMP RATE (Follower Mode) - ranges from 0.0001 to 1.9999 ratio units.
1 JOG SPEED - ranges from 0 to 99999 (or Display Unit Maximum).
1 JOG RAMP RATE - ranges from 1 to 99999.
2 ALARM - ranges from 0 to 99999.
1 GAIN - ranges from 0 to 99.
Note: Values may be programmed in the ranges listed, provided that the
maximum equivalent frequency does not exceed 20,971 Hz ( 20 KHz/sec for
Ramp Rate). If this occurs, a message will flash and the maximum is
automatically entered by the unit.
USER INPUTS
There are four programmable external user inputs and two programmable
front panel function keys. The options for each user input are the same, except
for the two function keys (F1/RUN & F2/STP), which have additional options.
No Mode:
If a user input terminal or a function key is activated, it will be ignored.
View Display 1-4:
Causes the selected indication display (1, 2, 3, or 4) to be displayed and held
from anywhere in the main display loop.
Change Display:
Causes the indication display to toggle to the next indication display.
Reset Alarm(s) Output:
Places the alarm(s) output(s) in its inactive state.
Setpoint Select/Toggle:
Selects Setpoint 1 or Setpoint 2 for the active speed (or ratio) setpoint. This
is a maintained select action for User Inputs 1 to 4, and a momentary toggle
action for F1 or F2.
Ramp Select/Toggle:
Selects Ramp 1 or Ramp 2 for the active acceleration and deceleration ramp
rate. This is a maintained select action for User Inputs 1 to 4, and a
momentary toggle action for F1 or F2.
Ramp Override:
Overrides the acceleration/deceleration ramp routine causing the unit to jump
to the ramp endpoint.
Setpoint Increment:
Only an external User Input can be used for this option. The currently active
speed or ratio setpoint is incremented when the User Input is made active. If
the input remains active for more than 5 display unit increments, the scroll
rate will progressively increase.
Setpoint Decrement:
Only an external User Input can be used for this option. The currently active
speed or ratio setpoint is decremented when the User Input is made active. If
the input remains active for more than 5 display unit increments, the scroll
rate will progressively increase.
Program Disable:
Only an external user input can be used for this option. When used with the
program disable DIP switch, this option can limit operator access to
programmable parameters.
Run (F1 only):
Pressing the F1 button causes the MDC to accelerate the motor from Stop
mode to the active speed setpoint using the active ramp rate.
R-Stop(F1 or F2 only):
Pressing the function key programmed for R-Stop causes the unit to
decelerate the motor from its active speed to Stop mode using the active ramp
rate.
F-Stop(F1 or F2 only):
Pressing the function key programmed for F-Stop causes the unit to execute
a fast stop, taking the motor from its current speed immediately to the stop
mode. The deceleration is limited only by the motor and drive.
Jog(F1 or F2 only):
This function is only available from the Stop mode. Pressing and holding the
function key programmed for Jog causes the unit to accelerate the motor to
the jog speed setpoint using the jog ramp rate.
ALARMS
Type Of Alarm:
High Alarm: Alarm output activates when the feedback input is greater than
or equal to the alarm value.
Low Alarm: Alarm output activates when the feedback input is less than or
equal to the alarm value.
Deviation Alarm: The alarm output activates when the feedback input is
outside a ± band.
Zero Speed Alarm: Alarm output activates when the feedback input receives
no input pulse for at least one second.
Disabled: The alarm output is inactive when disabled.
Phase:
Each output can have its active logic state set for Positive phase (ON) or
Negative phase (OFF).
Latched Or Boundary:
An alarm programmed for a latched output stays active until it is manually
reset by a User Input. An alarm programmed for boundary output stays active
as long as the alarm condition exists, after which the output returns to its
inactive state.
Fast Or Normal Update:
The normal update rate for the alarm outputs is once each second. The fast
update rate occurs at an interval less than or equal to 40 msec.
INDICATION DISPLAYS
If an indication display is to show two different numeric values, one for each
line, there will be a single or dual character mnemonic to the left of the numeric
value. Each line of each indication display can be programmed to show
mnemonics or a numeric value. The following list shows the single or dual
character mnemonics that will be displayed when value is selected and the
mnemonics for each programmable option.
STATUS DISPLAYS
Operating Status:
Setpoint 1, ramp rate 1, Stop mode
Alarm Output Status:
Alarm 1 active, alarm 2 inactive
Operating Status:
The operating status display indicates the currently active speed or ratio
setpoint (S1 or S2), the currently active ramp rate (R1 or R2), and the mode
of operation (RUN, STP, or JOG). An arrow will replace the “R” for the
currently active ramp rate indication when an actual ramp up or down is in
progress.
Alarm Status:
The alarm status display indicates that an alarm output is active when the
corresponding output number (1 or 2) is displayed. When an alarm output is
inactive, a dash is displayed.
