Red Lion MDC - Manual (Page 26)

PROGRAM DISPLAYS MENU
Each line of each Indication Display can be programmed individually to
show mnemonics or a numeric value for: Speed/Ratio Setpoint 1 or 2, Speed,
Ratio, % Deviation, % Output, Feedback Frequency, Lead Frequency, Alarm
1 or 2 setpoint and Trim. Or, each line may be programmed to one of the two
status displays: Operating Status or Alarm Output status. 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. This
will also be true if one line is programmed for operating status or alarm output
status. The flowchart on the following page shows only the Display portion:
DISPLAYS 1 TO 4
Each line of each display has the same programmable options. MNE is the
abbreviation for Mnemonics and VAL is for Value. The following list shows
the single or dual character mnemonics that will be displayed when VAL is
selected and the full mnemonic when MNE is selected:
VAL MNE DESCRIPTION
S1 99999 SETPT. 1 Speed or ratio setpoint 1
S2 99999 SETPT. 2 Speed or ratio setpoint 2
Sp 99999 SPEED Actual speed in user display units (feedback)
R 1.999 RATIO Actual feedback to lead input speed ratio
(follower mode)
%D 100.0 % DEV. % deviation of actual speed from target speed
%O 100.0 % OUTPUT Analog drive output- % of full scale voltage
FB 20971 FB. FREQ Feedback frequency in pulses/sec (Hz.)
LD 12000 LD. FREQ Lead frequency in pulses/sec (Hz.)
A1 99999 ALARM 1 Alarm 1 setpoint
A2 99999 ALARM 2 Alarm 2 setpoint
Tr 4095 TRIM Error correction in bits (-4095 to +4095)
(See Isolated Drive Output Calibration section)
Status displays:
Operating Status
(setpoint 1, ramp rate 1, Run mode)
Alarm Output Status
(alarm 1 inactive, alarm 2 active)
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.
SCROLL SPEED (SCRO.SPD)
The Indication Displays can be set to scroll automatically at a 2.5 or 5 second
scroll rate. Automatic display scrolling can also be set to NONE, in which case
the up and down arrow keys are used to scroll through the displays.
