Features and technical data

Applications
HGL is an optional hardware expansion for SIMODRIVE 611 for C axis
operation.
HGL allows the toothed–wheel encoder to be independently used as spindle
encoder for conventional spindle drives.
Mode of operation
The analog sinusoidal signals of the toothed–wheel encoder are fed to the con-
verter motor encoder connector for the closed–loop speed control.
The encoder signals are multiplied and converted into square–wave signals for
the higher–level closed–loop position control. These are fed to the numerical
control, once for spindle operation and once for C–axis operation.
Various multiplication factors can be selected using a rotary switch. In addition,
the phase sequence of the square–wave signals can be defined using the ro-
tary switch. This allows the direction of rotation of the encoder to be adapted to
the motor direction of rotation.
