T current ref 1 1st current reference value as a percentage of the Full load curr . The maximum value
possible depends on the Enable overload parameter.
Enable overload disabled T current ref 1 100% max
Enable overload enabled T current ref 1 200% max
T current ref 2 2nd current reference value as a percentage of the Full load curr . The maximum value
possible depends on the Enable overload parameter.
Enable overload disabled T current ref 2 100% max
Enable overload enabled T current ref 2 200% max
T current Ref Total current reference value as a percentage of the Full load curr value.
The total current reference value consists of the signed addition of T current ref 1 and T current Ref 2.
Example 1:
T current ref 1 = +50% T current ref 2-= +30%
T current ref = 50% + 30% = 80%
Example 2: T current ref 1 = +40% T current ref 2 = -60%
T current ref = 40-60% = -20%
The current reference value has an upper limit.
0 ... 10 V, 0 ... 20 mA and 4 ... 20 mA signals can be used when setting the reference value via terminals.
Reference set using input current, usually are with sign positive and they are used with biquadrant drives.
