3.11 Oscillator mode via analog interface
In oscillator mode, the speed of the stepping motor can be set via an
analog voltage on the ANA_IN input. The voltage range can be set on
the front panel from -10 V to +10 V. Available for units:
– with analog interface
Prerequisites:
– Manual mode via inputs/outputs inactive.
The following parameters must have been set (see chapter 3.3.1):
P02 Acceleration
P04 Maximum speed in CW and CCW sense of rotation.
P70 Voltage (
±
10 V) at maximum speed in CW sense of rotation.
P70 can be used to define the ANA_IN input voltage at which the
motor is to move at maximum speed in CW sense of rotation.
P71 Voltage (
±
10 V) at maximum speed in CCW sense of rotation.
P71 can be used to define the ANA_IN input voltage at which the
motor is to move at maximum speed in CCW sense of rotation.
The two graphics show:
➀
Normal case:
±
10 V input voltage (maximum resolution)
➁
Special case: Limited working range (reduced resolution)
NOTE
With the actions A70 and A71, the working range can be defined by
applying two voltages on the analog input; see chapter 3.3.5. The two
voltages are stored in the parameters P70 and P71.
P72 Zero window.
If the voltage on the ANA_IN input is within the range of the window
specified with P72, the motor is decelerated.
P74 Braking ramp with analog interface ANOZ.
P74 can be used for setting the deceleration at which the motor
comes to a standstill, if
– the AUTOM input is inactive;
– the STOP input is activated.
NOTE
If P74 = 0, the motor is decelerated at the value of P02.
