Hook Height Measurement
Hook Height Measurement provides a monitor parameter (U01-50) and analog output proportional to
the hook’s current position between a home position and a limit position. Hook height programming
is used in conjunction with the Electronic Programmable Limit Switch parameters. Reference Figure
5-10 for Hook Height configuration. The physical limit switch must be normally open (N.O.) to
prevent homing during a power-down or power loss.
Table 5-22: Hook Height Parameter Settings
NOTE: Motor revolutions (U01-51) will not go negative. If 0 motor revolutions has been reached
and the hoist continues in the Up (FWD) direction, the motor revolutions will remain at 0.
NOTE: An N.O. contact must be used for the Hook Height Home input.
Parameter Display Function Range Default Model
C03-13 Height Measure Number of motor revolutions from
the top of travel (FWD direction) to
the bottom of travel (REV
direction).
0–65535 Rev 250 VG+
C03-14 Hook Height Home Sets the MFDI to be used for
setting the Hook Height Home
position. Corresponding MFDI
must be programmed or OPE23
will be shown.
0–4 2 VG+
0 Home = UL2 N.O. Motor Revolutions is set to 0 when
UL2 N.O. is closed (H01-xx = 07).
1 Home = LL2 N.O. Motor Revolutions is set to C03-13
when LL2 N.O. is closed (H01-xx =
09).
2 Home MFDI Upper Motor Revolutions is set to 0 when
Hook Height Home is closed (H01-
xx = 67).
3 Home MFDI Lower Motor Revolutions is set to C03-15
when Hook Height Home is closed
(H01-xx = 67).
4 Home = UL3 N.O. Motor Revolutions is set to 0 when
UL3 N.O. is closed (H01-xx = 62).
C03-15 Hook Height Out Selects the output voltage for the
analog Hook Height monitor.
0, 1 0 VG+
0 0 Revs = 0% U01-50 = 0%, MFAO = 0V
1 0 Revs = 100% U01-50 = 100%, MFAO = 10V
