Output direction
The output direction of this box (power and encoder
cables) is selected at the time of mounting. Possible
directions are:
• to side A
• to side B
Side B is the output direction illustrated. The
dimensions for side A as output direction can be
obtained by turning the terminal box around the X axis.
Motor encoder
• Resolverfeedback (RSF)
• Resolverfeedback (RSF) with integal
multiturn absolute encoder
The dimensions are identical.
Holding brake:
• without
• with
The dimensions are identical.
Output shaft
• plain shaft (preferred type)
• with keyway per DIN 6885 sheet 1, ed. 08.68
