NOTE!
The PTC input via DIx digital input does not detect short-circuits in the thermistor, but this resource is
available via analog input. Refer to
Section 15.3 MOTOR OVERTEMPERATURE PROTECTION (F0078)
on page 15-4 .
v) MULTISPEED, ELECTRONIC POTENTIOMETER, FORWARD RUN/REVERSE RUN WITH 2
ND
RAMP
It combines the Multispeed, E.P. and Forward Run/Reverse Run with 2
nd
Ramp primary functions in the same
DIx digital input.
w) ACCELERATE E.P. - TURN ON / DECELERATE E.P. - TURN OFF
It consists of the Electronic Potentiometer function with capacity to enable the inverter by means of a pulse at the
start, and a pulse for the stop when the output speed is minimum (P0133).

12.6 DIGITAL OUTPUTS
The CFW500 can operate up to five digital outputs according to the selected interface plug-in module; refer to
Table 12.1 on page 12-1 .
The DO1 digital output is always relay, while DO2 is always transistor; the other outputs can be relay or transistor
according to the plug-in module. On the other hand, the digital output parameter configuration makes no distinction
in this aspect, as detailed description below. Besides, the transistor digital outputs are always NPN, that is, in
open collector (sink).
