SKT672-040-E Key Features
- Can implement stepping motor drive systems simply by providing a DC power supply and a clock pulse generator
- One of five drive types can be selected with the drive mode settings (M1, M2, and M3)
- Provides four freely selectable modes for the vector locus during microstepping drive: circular mode, one inside mode, a
- Phase retention even if excitation is switched
- The excitation phase state can be verified in real time using the MO1, MO2, and MOI signal output pins
- The CLK input counter block can be selected to be one of the following by the high/low setting of the M3 input pin
- The CLK and RETURN input pins include built-in malfunction prevention circuits for external pulse noise
- ENABLE and RESET pins provided. These are Schmitt trigger inputs with built-in 20kΩ (typical) pull-up resistors
- No noise generation due to the difference between the A and B phase time constants during motor hold since external exci
- Microstepping operation supported even for small motor currents, since the reference voltage Vref can be set to any valu
