This drive has a built in ramping pulse generator (oscillator) with adjustable speed, acceleration and deceleration. Oscillator speed range is 400–5,000 Hz. Speed can be set from on-board trimpot or ex- ternal pot. A jumper allows you to select the internal oscillator. In oscillator mode, the pulse input becomes a run/ stop signal: when this signal is set high, the motor accelerates to a preset speed and slews. Lowering the input signal causes the drive to decelerate to rest. The amplifier regulates motor current by chopping at a constant, inaudible frequency. Phase current is selected from 32 levels by a DIP switch. 2.50" 3.75" 0.125" 3.00" 0.25" 4.00" 0.15" 4x Ø.125 3.70" 1.50" 0.25" .875" 2x Ø.125 MECHANICAL OUTLINE Amplifier step direction +5 ext speed pot Step Sequencer Oscillator STEP/SLEW JUMPER current setting full step/ half step step dir accel decel speed adj A+ A– B+ B– to motor enable Optical Isolator Optical Isolator 12-35 VDC Optical Isolator BLOCK DIAGRAM Recommended motors for the 3535 O drive: Size 11 Size 14 Size 17 Size 23 ———— ———— ———— ———— HT11-012 5014-842 HT17-068 HT23-394 HT11-013 HT17-071 HT23-397 HT17-075 HT23-400 |
