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.
Configurable inputs for 2 or 3 wire control
Input impedance 250 ohms
Input impedance 100k ohms
1k to 10k ohms, 2 Watt minimum
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.
Parameter 46, setting 8 provides 4 preset speeds and 2 accel/decel times
Configurable inputs for control of 8 preset speeds and 2 accel/decel times
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
Sine weighted PWM with harmonic compensation
IGBT (Insulated Gate Bipolar Transistor)
Programmable
Adjustable from 2 kHz to 8 kHz in 100 Hz increments (factory default is 4 kHz)
Adjustable - Select from a family of boost curves
Trip free operation, coordinated for drive and motor protection. Programmable from 1% to 180%
of drive Output Current.

t overload protection - 150% for 60 seconds, 200% for 30 seconds (Provides Class 10 overload
protection). Percentage refers to Parameter 42 setting.
Flat response over speed range (no speed compensation)
Speed compensation below 25% of base speed
Speed compensation below 100% of base speed
0.1 to 600 seconds
0 to 100% of accel/decel time - not to exceed 60 seconds
4 modes (programmable)
0.1 to 600 seconds
Stops all PWM output
Applies DC voltage to the motor for 0 to 25 seconds
Applies DC voltage to the motor for 0 to 25 seconds with Auto Shutoff
