With the SRM there is no sign change, the stabilization is achieved with a positive
sign. This current limits the max. achievable speed and the minimum current can-
not be maintained above this speed (reason: prioritisation of current controller com-
ponents).
For SM and IPM without encoder, the sign must be changed depending on the
speed level to operate the motor in the field weakening. For this change, parameter
"Allowed time difference frequency to current" in the safety module is decisive.

minimal current (SM)
Parameter structure to define the behavior to set a mini-
mum current. Only synchronous machines of the type: SM
(SM,IPM,SRM), no asynchronous motors

min. current [%de80[1]]
Minimum current in % of the current measuring range end
value (de80[1] current scale value)
Calculation example: de80[1] = 100.0A, fc32[3]= 3%

ramping time
Ramp time, related to the rated motor current.
A ramp can be specified via this parameter in order to com-
pensate the missing current or to change the sign in the
stabilizing current.
Setting instructions:
Mode 1: > 10ms
Mode 2: < 10ms
