2. Functions

2.2 Two speed operation

NB: R1 = R2 > R3

The value in Register 1 must be the same value as Register 2

2.2 Three speed operation

NB: R1 > R2 > R3

The value in Register 1 must be larger than Register 2

NB:

The stop offset is only effective when R8 = 1xxxxx.

2.3 PID - An/- 10 V regulation (optional)

The setting is effected using Registers R50 to R66
