Function of analog output
• Actual speed
The reading is a percentage of the rated speed.
• Actual value
The reading is a percentage of the range between
the minimum
and maximum value.
• Resulting setpoint
The reading is a percentage of the external setpoint
range.
• Motor load
The reading is a percentage of the range between 0
and 200 % of the maximum permissible load at the
actual speed.
• Motor current
The reading is a percentage of the range between 0
% and 200 % of the rated current.
• Limit 1 exceeded and Limit 2 exceeded
This function is typically used for monitoring of
secondary parameters in the system. If the limit is
exceeded, an output, a warning or an alarm is
activated.
• Flow rate
The reading is a percentage of the range between 0
and 200 % of the nominal flow.
