Analog Output Setup

No activation is required for the analog output. The 4-20 mA Analog output is always available at the
corresponding terminals (see Section 5.3.3.8 Analog Output Example Wiring). The analog output follows and is
proportional to percent motor speed. This output must be calibrated for current output (4-20mA) versus percent
speed. See Section 8.1.4 Analog Output Calibration

Digital Output Setup

7.4.1 Multi-purpose Digital Outputs

Each of the 3 Digital OUTPUTS can be configured to represent:





Each output can be set as NORMALLY OPEN (N.O.) or NORMALLY CLOSED (N.C.). For example, if an output
is set to ON/OFF status and NORMALLY CLOSED, this means that when the motor is running (indicator lamp is
ON) the output will be CLOSED. A NORMALLY OPEN setup will give the opposite response.
Digital output circuits are transistor based and limited to 24 VDC maximum (500 mA current limit per output), see
Section 5.3.3.5 Digital Output Wiring Example (Open Collector/Drain), and Section 13 Specifications for more
information.

7.4.2 Testing Digital Outputs

The MPC VECTOR allows the user to test the three (3) digital outputs. To manually control the digital
output values, proceed to
Menu Map for navigation if necessary. The user can select the desired output by pressing the ENTER
key. Once an output is selected, the user can change the output by pressing UP/DOWN. Doing so will
activate and deactivate the selected output.
Once in the Digital Diagnostics Screen the user will see the following
D I N 1 2 D O U T 1 2 3
1 1
DOUT123 shows whether the digital output is activated (1) or deactivated (0) on digital outputs 1, 2, and
3, respectively. The example above shows Digital Outputs 1 and 3 activated and 2 deactivated. The
user has selected digital output 1 for activation/deactivation.
