3. Maintenance/troubleshooting
3.1 Maintenance
The motor and the controller do not normally require any maintenance.
However, it should be regularly checked that the cabling is not damaged and
that all fixing screws are securely tightened.
3.2 Motor diagnosis
Disconnect the supply voltage. Disconnect the motor cables from the control
unit. Measure the motor resistance between 1–2, 3–4 and 5–6. The values
should be:
15M: 30–90 Ohm; 25M: 5–15 Ohm; 35M: 5–15 Ohm
The resistance should not differ by more than 5 Ohm between the phases for
15M, and by no more than 2 Ohm for 25M/35M. Also check the insulation
resistance between 1–3, 1–5, 3–5, 1–earth, 3–earth and 5–earth.
WARNING! Residual voltage remains for up to 1 minute after
disconnection of the supply voltage. The test switch and the DIP
switches may only be adjusted when the supply voltage has been
disconnected
.
Note! When checking the insulation resistance, it is important to turn the
motor shaft slowly (at least one complete turn) in order to get a correct
measurement.
