Loop to control a system’s position.
Multiturn absolute encoder, MTG
Absolute position measurement over several revolutions. Digital AC
servo motors may optionally be fitted with multiturn encoders (absolute
measurement of the rotor position over 4092 revolutions).
Fan unit
Forced cooling with an external fan (optional)
Interface for exchange of position data.
Radial cooling
Forced cooling of the motor frame by means of a fan (optional) installed
radially to the motor axis to increase the nominal torque.
Referencing
Travelling to a reference point which helps to create an absolute
reference in an incremental measuring system.
Analog interface RF
Signal to activate the drive when power has been switched on.
Angle measuring unit
Inductive angle measuring unit that generates alternating voltages with
angle-dependent amplitude. Absolute measurement referred to 360
°
(cyclically absolute).
RSF
Position encoder for cyclical absolute measurement of the rotor position
on digital intelligent drives (resolver principle).
Continuous power dissipated by AC servo motors over one cycle through
a bleeder or, in the case of supply units with an energy recovery
capability, back into the mains when the motor is braking or in "generative
mode".
Lag error
The lag error in CNC machines with a position control loop is the
difference between the position command and the position actual value.
Factor enabling the assessment of how smoothly a machine runs
(effective value of vibration speed (r.m.s. value of vibration velocity)).
