| ^ Operation at 400, 800, 1600, 3200 and 500, 1000, 2000, 4000 steps/revolution. Motor phase current setting by means of a DIP-SWITCH. Up to four possible equidistant values between INF min. and INF max. can be set. ^ Automatic current reduction at motor standstill. ^ Possibility to switch off motor current with an external logic signal. ^ Protection against a short circuit at motor outputs. ^ Protection against under-voltage and over-voltage. ^ Overheating protection. ^ High efficiency CHOPPER with MOSFET final stage output. Two separated and co-working electronic circuits to ensure acoustic noise and mechanical vibration reduction at low and medium speed. |
