DOLD SAFEMASTER S Motion Monitors
DOLD SAFEMASTER S Motion Monitors
DOLD SAFEMASTER S covers standstill, speed and frequency monitoring through sensor-based and sensorless variants. The described sensorless standstill method evaluates remanent motor voltage, while other configurations use proximity-switch or encoder information.
Review Summary
A relevant monitoring family when permission for access or reduced-motion operation depends on an accepted drive state. Choose the exact measurement method and supported motor configuration; electrical-frequency monitoring and measured shaft speed should not be assumed identical in every mechanism.
