Reverse operation
If you want to operate the gear unit in cyclic reverse operation, observe the following information to ensure the lubrication
of the circulating gearing parts:
§
PE planetary gear units can be operated in reverse operation without any additional steps.
§
In vertical mounting positions (output shafts pointing up or down), the orientation of the output shaft is unimportant
when installing the machine.
§
In horizontal mounting positions, the output shaft for P/PH/PHQ/PHV planetary gear units must be oriented as follows
when installing the machine. The marks or the position of the feather key indicate the center position of reverse
operation.
