Weight
External Dimensions Refer to specifications for actuator for it is integrated with controller
Note 1 It is the power source to be supplied when compulsorily releasing the brake.
Note 2 Rush current passes for about 5ms after the power is injected (at 40qC).
The rush current value varies depending on the impedance of the power line.
Note 3 If the pulse train applies the open collector output, prepare AK-04 (option) separately to convert to the
differential type.
Note 4 The environmental specifications include the actuator main unit.
