4.1 Basic speed or torque control

This section shows the essential requirements for a very basic speed or torque control application.

Note that the arrangement of the contactor shown here allows continuous phase sensing on EL1/2/3.

VERY IMPORTANT see 4.2 Main Contactor operation, 4.3 Main contactor wiring options, 14 Installation.

WARNING. Do not allow coil supply to be externally interrupted.

Retro- fit relay logic is often the main culprit.

WARNING The phase order of EL1/2/3 must be the same as L1/2/3

For Torque control enter Torque ref into T6. (0 - 10V).

For speed control link T6 to +10V on T27.
