Terminals: M1 (Pr.38), M2 (Pr.39), M3 (Pr.40), M4 (Pr.41) or
M5 (Pr.42) for external Base Block control. Value 12 is for
normally open (N.O.) input, and value 13 is for a N.C. input.

Mx "Close": Operation available.
Mx "Open":Operation available.
Note: When a Base-Block signal is received, the AC drive will
stop all output and the motor will coast. When base
block control is deactivated, the AC drive will start its
speed search function and synchronize with the motor
speed, and then accelerate to the Master Frequency.
