PARAMETER DESCRIPTIONS
In this chapter, you can find information on all the parameters of your HVAC400 application. If other information is
necessary, see

Parameters MENU or contact your nearest distributor.
10.1
Motor Settings
10.1.1
Motor Nameplate Parameters
P3.1.1.1 MOTOR NOMINAL VOLTAGE (ID 110)
Find the value
Un
on the motor's nameplate. Find out whether the motor connection is Delta or Star.
P3.1.1.2 MOTOR NOMINAL FREQUENCY (ID 111)
Find the value
fn
on the motor's nameplate.
P3.1.1.3 MOTOR NOMINAL SPEED (ID 112)
Find the value
nn
on the motor's nameplate.
P3.1.1.4 MOTOR NOMINAL CURRENT (ID 113)
Find the value
In
on the motor's nameplate.
P3.1.1.5 MOTOR COS PHI (ID 120)
Find the value
cos phi
on the motor's nameplate.
P3.1.1.6 MOTOR NOMINAL POWER (ID 116)
Find the value
Pn
on the motor's nameplate.
P3.1.1.7 MOTOR CURRENT LIMIT (ID 107)
You can use this parameter to set the maximum motor current from the HVAC drive. The range of values for the
parameter is different for each enclosure size of the drive. When the current limit is active, the drive output
frequency is decreases.
NOTE:
The Motor Current Limit is not an overcurrent trip limit.
P3.1.1.8 MOTOR TYPE (ID 650)
You can use this parameter to set the type of motor in your process. Select the type of the motor. You can select
for example, asynchronous induction motor (IM) or synchronous permanent magnet motor (PM).
10.1.2
Motor Control Parameters
P3.1.2.1 SWITCHING FREQUENCY (ID 601)
You can use this parameter to set the switching frequency of the HVAC drive.
If you increase the switching frequency, the capacity of the HVAC drive reduces. To reduce capacitive currents in
the motor cable, when the cable is long, we recommend that you use a low switching frequency. To reduce the
motor noise, use a high switching frequency.
P3.1.2.2 MOTOR SWITCH (ID 653)
You can use this parameter to enable the Motor Switch function.
