750 [TrqTpr_Enable]
Enables/Disables the current/speed function. The current/speed
function allows you to change the current limits set in Pars 8
[Current Lim Pos] and 9 [Current Lim Neg] by setting up to five
setpoints using parameters [TrqTpr_Limx] and a threshold
speed in Par 756 [TrqTpr_Spd].
• “Disabled” = The limits current /speed curve is disabled
• “Enabled” = The limits current /speed curve is enabled

751 [TrqTpr_Lim0]
The current limit of the current/speed curve that operates
constantly up to the speed set in Par 756 [TrqTpr_Spd]. The
value specified in this parameter overrides the values specified
in Pars 8 [Current Limit Pos] and 9 [Current Lim Neg].

752 [TrqTpr_Lim1]
First reduced current limit of the current/speed curve. The value
defined in this parameter must be less than the value in Par 751
[TrqTpr_Lim0] and greater than the values in Pars 753
[TrqTpr_Lim2], 754 [TrqTpr_Lim3] and 755 [TrqTpr_Lim4].

value defined in this parameter must be less than the value in
Par 752 [TrqTpr_Lim1] and greater than the values in Pars 754
[TrqTpr_Lim3] and 755 [TrqTpr_Lim4].

defined in this parameter must be less than the value in Par 754
[TrqTpr_Lim3]. The drive will operate at this current limit up to
the value set in parameter 162 [Max Feedback Spd].
