MAX preset adjustment

9 MAX preset adjustment

MAX preset adjustment

9.1 ARMATURE VOLTAGE control mode (speed control)

Refer to "Figure 18 Jumper and link positions" on page 14.
When using AV mode, the

MAX

preset operates as a speed control:

•

With the top and bottom proportional gain links fitted, the

MAX

preset range

adjustment is ±4 V to ±25 V for a 5 V speed demand.

•

With the top and bottom proportional gain links NOT fitted, the

MAX

preset

adjustment is from ±8 V to ±50 V.

9.2 PID feedback (gain control)

When using PID feedback, the

MAX

preset becomes a gain control.
