Motor controller diagnostics

ExplainedHectare One firmware · 1.2.3

How to read what a metering motor controller reports about itself on the Motors screen — speed, error code, voltages, temperature, current, status bits and fault counters.

The Motors screen is also the diagnostic screen of a motor controller. It shows, live, what the controller reports about itself. Open it with “MENU” → “Service” → “Electric motors” (“Service” level). The working view of the same screen is described in Motors screen.

The “Registers” page of motor 1, standing.
  1. “Motor #1” — which motor is shown. (−) / (+) step to the previous / next motor.
  2. “Registers” — the name of the page.
  3. The status word — sixteen bits of the controller; a lit (yellow) cell is a bit that is set.
  4. The legend of the bits — the number and the name of each bit. Table below.
  5. “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.
  6. “Error code” / “Act.posit.” — the controller's own error number (codes), and the position it counts itself at.
  7. “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.
  8. “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 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 motor 1 on field 1.
The statistics page of motor 1 on field 1.

The faults this motor has collected on the chosen 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, overcurrent and overtemperature included — they have no counter of their own.
“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.
