Mounting system
Consider the following when mounting the torque motor on the axis structure:
• Only use new (unused) 󹪝xing screws.
• The mounting surfaces must be free of oil and grease.
• Carefully observe the maximum permissible screw-in depth of the 󹪝xing screws in the stator
and rotor according to the relevant installation drawing or the following table
• The minimum insertion depth for the 󹪝xing screws in the stator:
1.0 x d + section without threads (valid for 1FW6050 and 1FW6060)
1.3 x d (valid for 1FW6090 to 1FW6130)
1.0 x d (valid for 1FW6150 and higher)
• Minimum insertion depth of the 󹪝xing screws in the rotor 󹪞ange (in steel):
1.1 x d (valid for 1FW6050 and 1FW6060)
1.0 x d (valid for 1FW6090 to 1FW6290)
