Note: This parameter is displayed only when the drive is set to allow for user-set units (o1-03 = 3).
■
o1-11: User-Set Display Units Decimal Display
Determines how many decimal points should be used to set and display the speed reference.
Setting 0: No decimal point
Setting 1: One decimal point
Setting 2: Two decimal points
Setting 3: Three decimal points
■
o1-12: Length Units
Sets the units used for distance control and for the sheave diameter.
Note: This parameter determines whether the following parameters are set in millimeters or inches: o1-20, S5-11, S5-12, U4-42,
U4-33, and U4-44.
Setting 0: Millimeter units
Setting 1: Inch units
■
o1-20: Traction Sheave Diameter
WARNING! Make sure that the traction sheave diameter (o1-20), the deceleration distance (S5-11) and the stop distance (S5-12) are
all set to the correct units. If these settings are incorrect, the elevator will not stop at the designated location, overrun will occur, and
may cause serious injury or death. Before using stop distance control, make sure that parameter o1-20, S5-11, and S5-12 are set to
correctly.
Sets the traction sheave diameter.
