How to read what a metering motor controller reports about itself on the Electric motors screen — speed, error code, voltages, temperature, current, status bits and fault counters — and how to move through it by touch.

The Electric motors screen shows, live, what a motor controller reports about itself. Open it with a two-finger tap on the home screen → “Service” → “Electric motors”, or with “Electric motors” in the context menu of a motor — both at the “Agronomist” level. The working view of the motors is a different screen: Motors screen.

The “Registers” page of a motor, standing.
  1. “Mode” — tap it to switch the page: “Registers”, then “Statistics”.
  2. “Motor #” with a number — which motor is shown, here motor 1. Swipe right for the next number, left for the previous one.
  3. “Registers” — the name of the page. A universal controller has two register pages, “Registers-1” and “Registers-2”.
  4. The status word — sixteen bits of the controller; a lit (yellow) cell is a bit that is set.
  5. The legend of the bits — the number and the name of each bit. Table below.
  6. “Speed” / “Target speed” — what the shaft is doing against what the panel asked for. A gap that does not close is the first sign of a load the motor cannot carry.
  7. “Error code” / “Act.posit.” — the controller's own error number (codes), and the position it counts itself at.
  8. “Volt.mot.,mV” / “Volt.elec.,mV” — the voltage at the motor and at the electronics, in millivolts. A motor voltage far below the electronics voltage means the supply sags under load.
  9. “Temperat.,C” / “Current,mA” — the controller's temperature and the current it draws. Compare the current with “I_hilo,A” set for this motor (Configure the motor controllers).
The “Registers” page of a motor, standing.
Gesture What it does
Tap “Mode” Next page.
Swipe right / left Next / previous controller number. The numbers run from 1 to 127 and go round; a number without a controller shows nothing useful.
Two-finger tap The menu: “Change address”, “Configuration” — see Configure the motor controllers.
Three-finger tap, or long swipe up Close the screen.

The status bits

Bit Name Bit Name
0 Enable 8 Toggle
1 Error 9 CmdTgl
2 Warn. 10 CmdErr
3 Moving 11 StpHalt
4 Reach 12 LimCur
5 Limit 13 LimVel
6 FolErr 14 LimPos
7 HomDone 15 LimSVel

The legend is drawn in English on every panel, whatever its language: it is a bit map of the controller, not a message to the operator.

The fault counters

The Statistics page of a motor.
The Statistics page of a motor.

The “Statistics” page shows the faults this motor has collected on the active field — they are part of the field statistics, not of the motor:

Counter What it counts
“Jammed” The rotor stalled and the controller had to give up or back off.
“Disconnects” The controller stopped answering.
“Other” Everything else the controller reported.
“In failure” The distance in metres this motor spent in a fault state.

Each counter is white at zero and red once it is not. A red figure does not mean the motor is faulty now — it means it was, somewhere on this field, and the seed placed there is worth a look. To read another field, make it the active field first (Statistics screen).
