How do I scale the analogue outputs if my metering system is not the same as the drive outputs?
The analogue outputs have a maximum output of + or - 11.3V at + or - 5mA with 10V representing 100% by default. Each analogue output has a divider , offset control and can be set to rectified or bipolar. For example AOP1 is by default set to 715) SPD FBK % UNF, which is the unfiltered speed feedback at + or - 10V = + or - 100% speed. If your metering system requires this output to be 5V at full speed in a single direction only you would go to CONFIGURATION, ANALOG OUTPUTS, AOP1 SETUP and set 251) AOP1 DIVIDER to 2.0000 and 253) AOP1 RECTIFY EN to enabled. The only analogue output you cannot do this to is T29, the armature current output. It can be set to rectified or bipolar but cannot be scaled - if you need a scaled version of armature current you will have to use one of the other, scaleable, analogue outputs having set its GET FROM to the appropriate PIN, usually 134) ARM CUR % MON.
