Cycle time of the analog I/O-functions: 250 µs. An In 1 is read every 125 µs.
The actual values of the analog inputs/outputs are shown in the diagram of the connector X3.

Analog Inputs AN IN1 / AN IN 2

Dead Band
ASCII: ANDB
Suppresses small input signals.
The function is useful with OPMODE1: analog speed (without higher-level position control)
Setp. Offset
ASCII: ANOFFx
This is used to compensate the offset voltages of CNC-controls and the analog inputs 1 (ANOFF1) or 2
(ANOFF2). Adjust the axis to standstill while the setpoint = 0V.
Scaling
ASCII: VSCALEx
Scaling of the speed setpoint value.
ASCII: ISCALEx
Scaling of the torque setpoint value.
T.Setpoint
ASCII: AVZ1
You can enter a filter time constant here, for An In 1 (clock rate 8 kHz, 1st order filter)
Auto-Offset
ASCII: ANZEROx
This function carries out an automatic adjustment of the setpoint offset.
Conditions: analog inputs short-circuited, or 0V from the controls.
