5 Start Up

YASKAWA ELECTRIC TOEP C710616 27A YASKAWA AC Drive - A1000 Quick Start Guide 19

 Run Command Selection (b1-02)

Set parameter b1-02 according to the run command used.

 Acceleration/ Deceleration Times and S-Curves

There are four sets of acceleration and deceleration times which can be set in the C1- parameters. The default

activated accel/decel times are C1-01/02. Adjust these times to the appropriate values required by the application. If

necessary S-curves can be activated in the C2- parameters for softer accel/decel start and end.

 Reference and Run Source

The drive has a LOCAL and a REMOTE mode.

If the drive is operated in the REMOTE mode, make sure that the correct sources for the frequency reference and run

command are set in parameters b1-01/02 and that the drive is in the REMOTE mode.

The LED in the LO/RE key indicates where the Run command is input from.

 I/O Setup

Note: The default setting functions can be seen in the connection diagram on page 8.

 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.
