Parameter Reference
AC30 series Variable Speed Drive
Parameter Name No. Path Default Range Units Writable
The scale is a simple multiplication factor. The input voltage is converted to a percentage value. 1463 Anin 12 Offset is added and the
result is multiplied by Scale. The result is presented in parameter 1182 Anin 12 Value .
Anin 13 Offset 1465
Same as PNO 1461
0.00 Min to Max %
ALWAYS
The offset is expressed as a percentage of the hardware range. For example an offset of 10% is equivalent to 1V on the input.
The offset is added to the measured value.
Anin 13 Scale
1466 Same as PNO 1461 1.0000 Min to Max ALWAYS
The scale is a simple multiplication factor. The input voltage is converted to a percentage value. 1465 Anin 13 Offset is added and the
result is multiplied by Scale. The result is presented in parameter 1183 Anin 13 Value .
RTC Trim 1187
Parameters::Option IO::General Purpose
IO
0 -40 to 40
ALWAYS
A trim value that may be used to speed up or slow down the Real Time Clock on the IO option. A positive trim value will cause the RTC
to run faster, an negative value causes the RTC to run slower. Refer to the AC30V General Purpose I/O Option manual for more
details.
Once programmed, the RTC trim affects the operation of the RTC both in battery backed up mode and normal running mode.
Analog input Scale and Offset
The input signal is converted to a percentage of the hardware range, that is -10V…10V is represented as -100 to 100%. The Offset is then added to
this input and the result of this is multiplied by the Scale factor. The result is presented in the Value parameter.
