7 Drive Machine Data (SIMODRIVE Drive MD)
7.1.2 MSD MD (data description - SW 3)
313
Default value
0
The I/f control diagnosis aid is activated by entering bit 0 = 1. This control is used to check
encoder faults. A variable speed (without encoder evaluation) can be specified via MD 311
(current) and MD 312 (frequency).
Bit 0
Bit 1-15
316
Default value
–
Display machine data for the current controller P gain. The current controller P gain is
calculated according to the motor, converter and converter switching frequency and can be
corrected by an offset in machine data MD 116 (P-gain current controller motor 1) and MD 278
(P-gain current controller motor 2). The resulting value is displayed in MD 316. When the star-
delta switchover function is enabled, the display is referred to the currently active operating
mode.
337
Default value
300
Input of creep speed of angle controller. At speeds above the value entered here, the I-action
component of the phase current controllers is disabled and the angle controller of the FCS
(Frequency-Compensated Spindle drive) control enabled.
338
Default value
25
Input of hysteresis for creep speed in MD 337. The value corresponding to half the hysteresis
width in rev/min must be entered.
399
Default value
–
Display machine data for the data version of the machine data set.
