This drive has a built in ramping pulse generator (oscillator) with adjustable speed, acceleration and deceleration. Oscillator speed range is 0– 5,000 Hz. Speed can be set from on-board trimpot or external 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 16 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 BLOCK DIAGRAM Amplifier Optical Isolator step direction com ext speed pot enable Step Sequencer Oscillator STEP/SLEW JUMPER current setting 50% idle full step/ half step step dir accel decel speed adj A+ A– B+ B– to motor Optical Isolator 12-35 VDC Optical Isolator Recommended motors for the 2035 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 |
