Figure 71: Torque current limit
Bit 1 and 3:
Dependent of the motor type and the controller FW version the following modes are avail-
able to calculate the "Max. torque current" Z19.8–.
X = independent of that
Standard load mode (default setting):
m Dependent of the field weakening and the external total current limit
m Dependent of 138.1 bit 1 at the ASM
m Z19.8– is calculated from "Max. drive current actual value" Z19.5– and "Max. field
current amplitude" Z19.7– (at the ASM with 138.1 bit 1 = 1: "lsd set value" Z47.2–
instead of the parameter Z19.7–).
Current mode
m Independent of the field weakening and the external total current limit.
m Independent of 138.1 bit 1.
m Z19.8– is calculated from the "Max. drive current" Z19.6– and the "Magnetizing cur-
rent" Z107.14– (ASM) or field weakening = 0 (SM).
Details about the effect of the standardization modes in the "Max. torque current" are de-
scribed in the parameter Z19.8–.
