5 Start Up

I/O Setup
Note: The default setting functions can be seen in the connection diagram on page 13.

Multi-Function Digital Inputs (H1-)
The function of each digital input can be assigned in the H1- parameters.

Multi-Function Digital Outputs (H2-)
The function of each digital output can be assigned in the H2- parameters. The setting value of these parameters
consist of 3 digits, where the middle and right digit set the function and the left digit sets the output characteristics (0:
Output as selected; 1: Inverse output).

Multi-Function Analog Inputs (H3-)
The function of each analog input can be assigned in the H3- parameters. Input A1 and A3 are set for -10 to +10 Vdc
input. A2 is set for 4-20 mA input.
NOTICE: If the input signal level of input A2 is switched between voltage and current, make sure that DIP switch S1 is in the correct
position and parameter H3-09 is set up correctly.
NOTICE: When using analog input A3 as PTC input, set DIP switch S4 to PTC and parameter H3-06 = E.

Multi-Function Analog Outputs (H4-)
Use the H4- parameters to set up the output value of the analog monitor outputs and to adjust the output signal
levels. When changing signal levels in parameter H4-07/08, make sure jumper S5 is set accordingly.

Test Run
Perform the following steps to start up the machine after all parameter settings have been done.
1.
Run the motor without load and check if all input, outputs and the sequence work as desired.
2.
Connect the load to the motor.
3.
Run the motor with load and make sure that there is no vibrations, hunting or motor stalling occurs.
After taking the steps listed above, the drive should be ready to run the application and perform the basic functions. For
special setups like PID control etc. refer to the Technical Manual.
