5.2.8 Hook Height Measurement
Hook Height Measurement is an IMPULSE•VG+ Series 4 feature that 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.
for Hook Height configuration. The physical limit switch must be normally open (N.O.) to prevent
homing during a power-down or power loss.
NOTE:
The F1 and F2 keys can be used for homing the hook height. This can be useful for zeroing out the hook
height without the need of a digital input. See parameters H01-09 and H01-10.
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.
