Pr.09 BOOST VOLTAGE
This parameter determines the minimum voltage while output frequency is low.
Pr.10 BASE_FREQUENCY (HZ)
Pr.11 BASE VOLTAGE (%)
These two parameters are determined by the motor's rated frequency and voltage.

Pr.12 PWM_CARRIER
PDA/PDE/PDH series:
series: Defines the maximum carrier frequency. When running frequency > Pr.14, the carrier frequency will be the
value of Pr.12, otherwise it is the value of Pr.13.
PDAN series:
Pr.12 is composed of two parameters:
Pr.12 = xx.y,
separated by decimal point
.
xx is used to define
PWM CARRIER
, y is used to defined
CARRIER TRANSFER POINT.
MINIMUMCARRIER
is fixed frequency 2KHz.
When running frequency > Transfer point , the carrier frequency will be the value
xx
(PWM Carrier), otherwise it is
2KHz (Minimum Carrier).

Output Frequency (Hz)
Pr.13 PDA/PDE/PDH series: MINIMUM_CARRIER
Defines the minimum carrier frequency.
PDAN series: MODBUS Elapse time
When RS485 port is defined as MODBUS protocol, this parameter defines the maximum elapse time between two
receiving bytes.
Pr.14 PDA/PDE/PDH series: CARRIER_TRANSFER_POINT
Defines the transfer point of output frequency, when carrier frequency reaches Pr.12.
Note: Select lower carrier frequency while inverter is running at low output frequency (Hz) can decrease
vibration
effect.

PDAN series: Thermistor type
Defines the Thermistor type, contact factory when board changed.
Pr.15 UPPER_FREQUENCY_LIMIT
Defines maximum possible output frequency (Hz) while running. Refer to Pr.10.
Pr.16 LOWER_FREQUENCY_LIMIT
Defines minimum possible output frequency (Hz) while running. Refer to Pr.10.
