Consult factory for maximum
speed allowance.
Note 8: 2 x analog channels available. Default settings are Channel 1 (voltage/current) – torque.
Channel 2 (voltage/current) – speed or power, if ordered.
Note 9: At very high speeds, for better balance the factory recommend plain or splined shafts.
Note 10: Transducers fitted for IP65 will have running speeds considerably reduced, increased drag torque and accuracy can
be affected.
