Quick installation guide – ACS355 5
1)
AI1 is used as a speed reference if vector mode is
selected.
2)
See parameter group 12 CONSTANT SPEEDS:
3)
0 = ramp times according to parameters 2202 and
2203.
1 = ramp times according to parameters 2205 and
2206.
4)
360 degree grounding under a clamp.
Tightening torque = 0.4 N·m / 3.5 lbf·in.
