Control Features
 
Control Input Type
 
For dry contact closure input - drive has an internal 12V power supply that provides 10mA (typical) 
current. Also accepts open collector/solid-state input with maximum leakage current of 50µA. 
Optional 24V DC interface allows use of 24V DC “sink logic” inputs.
 
Start, Stop, Forward/Reverse
 
Configurable inputs for 2 or 3 wire control
 
Analog Input (4 to 20mA)
 
Input impedance 250 ohms
 
Analog Input (-10 to +10V DC)
 
Input impedance 100k ohms
 
External Speed Potentiometer
 
1k to 10k ohms, 2 Watt minimum
 
PI Control
 
Users of Firmware Version FRN 7.05 and earlier use Parameter 46 setting 9 to activate the PI 
Control function.
Users of Firmware Version FRN 7.06 can use Parameter 46 settings 0 through 7 and 9 to activate 
the PI Control function.
 
SW1, SW2
 
Parameter 46, setting 8 provides 4 preset speeds and 2 accel/decel times
 
SW1, SW2, SW3
 
Configurable inputs for control of 8 preset speeds and 2 accel/decel times
 
Programmable Output
 
(from C relay contact)
Resistive Rating: 0.4A at 125V AC, 0.2A at 230V AC, 2A at 30V DC
Inductive Rating: 0.2A at 125V AC, 0.1A at 230V AC, 1A at 30V DC
Programmable for eleven different functions
 
PWM Algorithm
 
Sine weighted PWM with harmonic compensation
 
Switching Device
 
 (3-Phase Output) IGBT (Insulated Gate Bipolar Transistor)
 
V/Hz Ratio
 
Programmable
 
Carrier Frequency
 
Adjustable from 2 kHz to 8 kHz in 100 Hz increments (factory default is 4 kHz)
 
DC Boost
 
Adjustable - Select from a family of boost curves

I
 
2
 
t overload protection - 150% for 60 seconds, 200% for 30 seconds (Provides Class 10 overload 
protection). Percentage refers to Parameter 42 setting.
 
Overload Pattern #0
