5 Start Up
Leveling Speed Priority is Selected and the Nominal Speed Input is Not Assigned (d1-18 = 2, H1-
The drive runs at nominal speed (d1-19) when no speed selection input is set. When the leveling speed signal is set, the
drive decelerates to the leveling speed. The leveling speed signal has priority over all other speed signals.
CAUTION! This sequence can be risky if the speed selection doesn't work for some reason (broken wire, etc.)
I/O Signal Setup
Note: The default setting functions can be seen in the connection diagram on page 10.
Multi-Function Digital Inputs
Assign functions to each digital input terminal using the H1-
Multi-Function Digital Outputs
Determine the function for each digital output terminal with the H2-
parameters consists of three digits, where the middle and right digit determines the function, and the left digit sets the
output characteristics. The output characteristics can be either "Output as selected" (0) or "Inverse output" (1).
Multi-Function Analog Inputs
The function of each analog input can be assigned in the H3-

Acceleration Ramp, Deceleration Ramp, and Jerk Settings
The acceleration and deceleration ramps are set in the parameters C1-01 and C1-02, while the jerk settings are set in the
C2- parameters as shown in the figure below.
The way of setting these parameters and their setting units change with parameter o1-03 as shown below:
