Introduction
VMAX Value
The maximum speed VMAX must be such that the resultant frequency satisfies the following condition:
1.8 kHz < FMAX < 900 kHz with FMAX = VMAX x m / RESOL m = 2 with a x1 incremental encoder or an absolute encoder, m = 4 with a x4 incremental encoder.
The condition on the maximum frequency is translated onto the VMAX value by the following relation:
108 x RESOL / m < VMAX < 54000 x RESOL / m restricted to the following limits:
270 < VMAX < 270000
Note: VMAX and RESOL are expressed in the units defined in the configuration screen, either RESOL in microm and VMAX in mm/min, or RESOL in mm and
VMAX in m/min, etc.
Authorized speed
Whatever the speed programmed in the instructions, the module is authorized to operate at a speed equal to VMAX + 10%, on the transitories, in order to reduce following error.
