LCD Display
Displays the source for the Run command as XY-nn.
X: Indicates which Run source is used:
0 = OFF
1 = AUTO
2 = HAND
Y: Input power supply data
0 = HOA keypad
1 = External terminals
3 = Serial communications (APOGEE FLN, BACnet,
MEMOBUS/Modbus, or Metasys N2)
4 = Communication option card
nn: Run command limit status data
Run Cmd Source 00: No limit status.
01: Run command was left on when stopped in the PRG mode
02: Run command was left on when switching from LOCAL to
REMOTE operation
03: Waiting for soft charge bypass contactor after power up (Uv
or Uv1 flashes after 10 s)
04: Waiting for "Run command prohibited" time period to end
05: Fast Stop (digital input, HOA keypad)
06: b1-17 (Run command given at power-up)
07: During baseblock while coast to stop with timer
08: Frequency reference is below minimal reference during
baseblock
09: Waiting for Enter command
Displays the drive control data set by MEMOBUS/Modbus
MEMOBUS Ref Reg communications register no. 0001H as a four-digit hexadecimal
number.
Displays drive control data set by an option card as a four-digit
Option Ref Reg
hexadecimal number.
LCD Display
Displays the PID feedback value.
PID Feedback 1
Displays the amount of PID input (deviation between PID
PID Input
setpoint and feedback).
Displays PID control output.
PID Output
Displays the PID setpoint.
PID Setpoint
Displays the second PID feedback value if differential feedback
PID Feedback 2
is used (H3-oo = 16).
Displays the difference of both feedback values if Differential
Feedback is used (U5-01 - U5-05).
If PID Square Root Feedback or Differential Feedback are
enabled, U5-01 ≠ U5-06.
If PID Square Root Feedback or Differential Feedback are NOT
enabled, U5-01= U5-06.
Displays the Frequency reference value at AUTO Mode.
AUTO mode Fref
Displays the Frequency reference value at HAND Mode.
HAND mode Fref
Displays Custom PID output. U5-14 shows the upper 4 digits.
