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.
15.1 Analog Inputs AN IN1 / AN IN 2
Dead Band
ASCII: ANDB
Default: 0 mV valid for OPMODES 1+3
Suppresses small input signals.
The function is useful with OPMODE1: analog speed (without higher-level position control)
Setp. Offset
ASCII: ANOFFx
Default: 0 mV valid for all OPMODES
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
Default: 3000 valid for OPMODE 1
Scaling of the speed setpoint value. entry: xx rpm / 10 V
ASCII: ISCALEx
Default: Peak current valid for OPMODE 3
Scaling of the torque setpoint value. entry: xxA/10V
T.Setpoint
ASCII: AVZ1
Default: 1 ms valid for OPMODE 1
You can enter a filter time constant here, for An In 1 (clock rate 8 kHz, 1st order filter)
Auto-Offset
ASCII: ANZEROx
Default: - valid for all OPMODES
This function carries out an automatic adjustment of the setpoint offset.
Conditions: analog inputs short-circuited, or 0V from the controls.
