displayed on a pointer instrument via the analog module output.
In SIMOCODE pro, representation of the effective phase currents or the
maximum current (current IL_1, IL_2, IL_3, max. current I_max) corresponds
to the selected range as a percentage of the parameterized set current I
– 2 A motor current corresponds to 100 % of I
– 8 A motor current corresponds to 400% of I
– The smallest unit for the effective motor current in SIMOCODE pro is 1%
(see measured values data record 94).

As a result,
– The "Start value of value range" to be selected is:
– The "End value of value range" to be selected is:

AM Output
When the parameterized "Output signal" = 0 - 20 mA:
– 100 % motor current corresponds to: 0 mA at the analog module output
– 400% motor current corresponds to: 20 mA at the analog module output.
When the parameterized "Output signal" = 4 - 20 mA:
– 100 % motor current corresponds to: 4 mA at the analog module output
– 400% motor current corresponds to: 20 mA at the analog module output.
