Programmable analog output
One programmable current output (0 to 20 mA) is available. Analog output signal
can be inverted, filtered and the maximum and minimum values can be adjusted.
The analog output signals can be proportional to motor speed, output frequency,
output current, motor torque, motor power, etc. The update cycle for the analog
output is 2 ms.
Analog output can be controlled with sequence programming. It is also possible to
write a value to an analog output through a serial communication link.

Programmable digital inputs
The drive has five programmable digital inputs. The update time for the digital inputs
is 2 ms.
One digital input (DI5) can be programmed as a frequency input. See section
Frequency input on page 105 .
