GFK-3111A PACMotion VFD AC Variable Speed Drive User Guide 33
Analog Outputs
Two analog outputs are available, and may be used for 0 – 10 Volt Signal (max load 20 mA), 0 – 20 mA, 4 – 20
mA or a digital +24 Volt DC, 20 mA output. The parameters to select function and format are as follows.
Table 19: Analog Output Function & Format Parameters
Analog Output Function selected by Format selected by
Analog Output 1 P2-11 P2-12
Analog Output 2 P2-13 P2-14
These parameters are described more fully in section Parameter Group 2 - Extended Parameters on page 56.
Auxiliary Relay Outputs
Two relay outputs are available, which are intended to be used to switch external resistive loads up to 5 A at
230 V AC or 30 V DC.
Relay 1 has both normally open and normally closed contacts available. Relay 2 provides a simple open or
closed contact.
The relay output function may be congured using parameters P2-15 and P2-18, which are described in
section Parameter Group 2 - Extended Parameters on page 56.
Motor Thermal Overload Protection
Internal Thermal Overload Protection
PACMotion VFD has internal motor overload protection (current limit) set at 150% of FLC. This level may be
adjusted using P4-07.
The drive has an in-built motor thermal overload function; this is in the form of an “I.t-trP” trip after delivering
>100% of the value set in P1-08 for a sustained period of time (e.g. 150% for 60 seconds).
Motor Thermistor Connection
Where a motor thermistor is to be used, it should be connected as follows:

Compatible Thermistor: PTC Type, 2.5 kΩ trip level.
Use a setting of P1-13 that has DI5/AI2 function as
E-TRIP “External Trip”, e.g. P1-13 = 6. Refer to section
Digital Input Conguration Parameter P1-13 on page
50 for further details.
Enable the Motor PTC Thermistor Input function in
parameter P2-33.
