Analog signal
Input
Three inputs, 12-bit A/D, 0
–10V
Output
Two outputs, 10-bit D/A, 0
–10V (internal
parameter output can be set through the LED
panel or external HMI)
Power supply
Output
Used to externally provide 15V reference power
supply. Max. output current: 50mA
Communication
Function
Four types of filed bus available:
(Standard) Modbus
(Optional) EtherCAT, CANopen, and PROFINET
LED panel and keypad
Six-digit display, with four function keys
External HMI
The external HMI communicates with the drive
through the RS485 interface to set parameters,
copy parameters, and so on.
Control
function
performance
Process control
Supported input: analog input, internal input,
communication input, RS485 continuous input,
CANopen input, EtherCAT input, and
PROFINET input
Speed control
