7.3.6 Menu 6 - IO configuration
This menu contains parameters related to the setup of the drive inputs and outputs. To use an analog input or frequency input as a drive reference,
the appropriate value should be set in a
Frequency Reference 1 Selector
(P2.21) or similar parameter.
P6.01
T2 Analog Input 1 Type
Range:
0 to 5
Default:
3 (4 - 20 mA)
P6.02
T4 Analog Input 2 Type
Range:
0 to 5
Default:
0 (0 – 10 V)
Defines the type of input.
The analog inputs can be set up as voltage or a current type as defined above with a resolution of 11 bits.
The analog inputs can also be used as digital inputs where the switching thresholds are at 7 V and 8 V. When used as a digital input the terminal
does not sink or source current so if the input is not being driven, an appropriate pull up or pull down resistor must be fitted externally.
In 4-20 mA current input modes, a current input less than 3 mA is detected as a current loop loss which can be used to indicate a wire break.
The value of these parameters can be set by
Frequency Reference Configuration
(P2.03).
P6.03
T6 Analog Output Type
Range:
0 to 2
Default:
2 (4 - 20 mA)
Defines the type of output.
The analog output can be set up as voltage or a current type as defined above. The absolute value of the chosen parameter is scaled such that 10
V or 20 mA is equivalent to the parameter's maximum value. It can be further scaled by
T6 Analog Output Scaling
(P6.07).
P6.04
T11 Digital IO 1 Type
Range:
0 to 4
Default:
0 (Digital Input)
Defines the digital IO type for digital I/O 1.
As a Digital Output, the maximum source current is 50 mA (but 100 mA total limit on digital output, 24 V output and 485 port), and there is a
6 - 7 k
Ω
internal pull down resistor to 0 V which will sink some current.
As a Frequency Output, 10 kHz is equivalent to the maximum value of the output variable. This can be scaled using
T11 Frequency/
PWM Output Scaling
(P6.11). The resolution of the frequency output is 0.02 %.
As a PWM Output, the output frequency is fixed at 1 kHz and 100 % duty is equivalent to the maximum value of the output variable. This can
be changed using
T11 Frequency/PWM Output Scaling
(P6.11). The resolution of the PWM output is 0.02 %. In this mode the output can be
connected to an analog meter for monitoring purposes only as the PWM amplitude only has the accuracy of the 24 V output voltage. The output
may require filtering before connecting to a meter if the meter used is responsive enough to pick up the 1 kHz output frequency.
The value of this parameter can be set by
Frequency Reference Configuration
(P2.03).
