Датчики SIMODRIVE– это пристраиваемые оптоэлектронные датчики для регистрации участков траекторий, углов вращения или скоростей станков. Они могут использоваться вместе с ЧПУ, программируемыми логическими контроллерами, приводами и устройствами индикации положения, например:
- системами привода SINAMICS
- системами управления движением SIMOTION
- ЧПУ SINUMERIK
- программируемымилогическимиконтроллерамиSIMATIC
- системамиприводаSIMODRIVE и SIMOVERT MASTERDRIVES
