Output Terminal Functions - Omron VARISPEED L7 Manual

Output Terminal Functions

The digital multifunction outputs can be set to several functions using the H2-01 to H2-03 parameters (termi-
nal M1 to M6 function selection). These functions are described in the following section.

Zero Speed (Setting: 1)
* The Zero Speed Level depends on the control mode. It is 0.1 Hz for Closed Loop Vector, 0.5 Hz for Open Loop Vector and 1.2 Hz for V/f control.
