34 Basic application
4.1 Basic speed or torque control
This section sho ws the essential requi rements for a very basic speed or torque control application.
Note that the arrangement of the contactor shown here allo ws continuous phase sensing on EL1/2/3.
VERY IMPORTANT see 4.2 Main Contactor operation, 4.3 Main contactor wiring options, 14 Installation.
Note. B1, B2 Fan supply is 110V AC 50VA for PL/X185-265 and 240V AC 100VA for PL/X 275-980.

Terminals 1 - 36 are located on the
bottom edge of the upper control
board arranged as 3 blocks of 12.
Terminals 2 -12, 14 - 24, and 31
are programmable.
Their default function is shown here.

allow coil supply to be
externally interrupted.
Retro- fit relay logic is
often the main culprit.

The phase order
of EL1/2/3 must
be the same as
L1/2/3
For Torque control
enter Torque ref
into T6. (0 - 1 0 V).
For speed control
link T 6 to + 1 0V
on T 27.
