Internal supplies available
Short-circuit and overload protection:
One +10 V (-0 / +8%) supply for setpoint potentiometer (2.2 to 10 kΩ), maximum current 10 mA
One +24 V supply (minimum 19 V, maximum 30 V) for logic inputs, maximum current 100 mA
Configurable analog inputs
Three configurable analog inputs AI1, AI2, AI3.
AI1: Analog input 0 to +10 V (maximum safe voltage is 30 V)
• Impedance: 30 kΩ
• Resolution: 0.01 V, 10-bit converter
• Precision: ± 4.3% of maximum value
• Linearity: ± 0.2% of maximum value
• Sampling time: 8 ms
• Shielded cable length: 100 m (328 ft) maximum
AI2: Analog input 0 to +10 V (maximum safe voltage is 30 V)
Bipolar analog input 0 to ±10 V (maximum safe voltage is ±30 V)
The + or - polarity of the voltage on AI2 affects the direction of the setpoint and therefore the direction of rotation.

or
AOC can be configured as a 24 V logic output with a minimum load impedance of 1.2 k
Ω.
Analog voltage output AOV
or
Analog current output AOC
or
Logic voltage output on AOC
Can assign either AOV or AOC, but not both.
Configurable relay outputs
R1A is a N.O. contact.
R1B is a N.C. contact.
R1C is the common.
R1 is programmable—factory set as a fault
relay (R1A is closed and R1B is open when the
controller is powered with no fault)
R2A, R2C
N.O. contact of programmable relay R2

Acceleration and deceleration ramps
Ramp profiles:
• linear, can be adjusted separately from 0.1 to 999.9 s
• S, U, or customized
Automatic adaptation of deceleration ramp time if braking capacities are exceeded,
possible inhibition of this adaptation (use of braking resistor).
DC injection braking
DC injection braking can be initiated:
• By a signal on a programmable logic input
• Automatically as soon as the estimated output frequency drops to < 0.5 Hz, period adjustable from 0 to 30 s or
continuous, current adjustable from 0 to 1.2 In
Signaling
on the drive local keypad display
• One red LED indicating the presence of drive voltage
• Four 7-segment displays
• Two CANopen status LEDs (RUN and ERR)
Scan time for reference change
5 ms
