6.6 Indexer Timing Requirements
Typical limits are at TJ = 25°C and VVM = 24 V. Over recommended operating conditions unless otherwise noted.
| NO. | MIN | MAX | UNIT | ||
|---|---|---|---|---|---|
| 1 | ?STEP | Step frequency | 500(1) | kHz | |
| 2 | tWH(STEP) | Pulse duration, STEP high | 970 | ns | |
| 3 | tWL(STEP) | Pulse duration, STEP low | 970 | ns | |
| 4 | tSU(DIR, Mx) | Setup time, DIR or MODEx to STEP rising | 200 | ns | |
| 5 | tH(DIR, Mx) | Hold time, DIR or MODEx to STEP rising | 200 | ns | |
(1) STEP input can operate up to 500 kHz, but system bandwidth is limited by the motor load.
