Want to increase Spindle RPM

Axis power drives Control moduleis 6SN1118-0NH11-0AA0. Spindle command max voltage is + or - 10V DC.At present spindle speed is limited to max 56 RPM at 50 Hz. I can increase the frequency at can get 90 spindle RPM. The same thing I would like to achieve from program command i.e. M03 S90. But even then getting maximum spindle RPM as 56. Can any one guide me as what parameters needs to be adjusted so that 90 spindle RPM can be achieved by program. Thanks in advance. DEEP.

Could also check in the Setting data where spindle maximum and minimumSpeed is defined. (offset parameter softkey> Setting data) hope this will solve your problem..... Ekalavya
