VFD-S Series

5-28

d13, d14 External Base Block:

Parameter values d13, d14 program Multi-Function Input Terminals: M1 (Pr.4-04), M2

(Pr.4-05), M3 (Pr.4-06), M4 (Pr.4-07) or M5 (Pr.4-08) for external Base Block control. Value

d13 is for normally open (N.O.) input, and value d14 is for a normally closed (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 free run. 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 Master

Frequency.
