7.2.3 Speed Reference Parameters

P0121 – Speed Reference via HMI
Adjustable
0 to 18000 rpm
Range:
Description:
Parameter P0121 stores the speed reference via HMI (P0221 = 0 or P0222 = 0). When the keys "
active and the HMI in the view mode of the HMI, the value of P0121 is increased and shown on the HMI main
display. Besides, the P0121 is used as input for the reference backup function.
The direction of rotation is defined by parameters P0223 (LOCAL) or P0226 (REMOTE).
NOTE!
The maximum setting value of parameter P0121 via HMI is limited by P0134.
P0122 – Speed Reference for JOG
Adjustable
0 to 18000 rpm
Range:
Description:
During the JOG command, the motor accelerates up to the value defined in P0122, following the acceleration ramp
set according to P0105. This command may be activated by any of the sources, as per
FOR LOGICAL COMMAND AND SPEED REFERENCE on page
The direction of rotation is defined by parameters P0223 (LOCAL) or P0226 (REMOTE).
The JOG command is only effective with the motor stopped.

7.2.4 Analog Input AIx and Frequency Input FI

The behaviors of the analog and frequency inputs are described in details in
page
12-1. Thus, after the proper signal treatment, it is applied to the ramp input according to the
SELECTION FOR LOGICAL COMMAND AND SPEED REFERENCE on page

7.2.5 13-Bit Speed Reference

The 13-bit speed reference is a scale based on the motor rated speed (P0403). In the CFW501, parameter
P0403 is taken as the base to determine the speed reference. Thus, the 13-bit speed value has a range of 16
bits with signal, that is, -32768 to 32767; however, the rated frequency in P0403 is equivalent to the value 8192.
Therefore, the maximum value in the range 32767 is equivalent to four times P0403.
The 13-bit speed reference is used in parameters P0681 or P0685 and system marker for the SoftPLC, which
are related to the interfaces with communication networks and SoftPLC function of the product.
