8.5 Rotary encoder
DANGER:
Risk of fatal injury when operating or changing tools without standstill monitoring!
Material damage when operating without rotation monitoring
If the frequency converter is switched on, the standstill (speed = 0 U/min) of the spindle shaft (standstill
monitoring) must be continuously observed.
This particularly applies to the following:
•
Persons within the separating safety equipment area
•
Maintenance and repair tasks
• Manual tool exchange
• Automatic tool exchange
• Commissioning
►
Operate the motor spindle only when the standstill monitoring is actively evaluated and monitored.
►
Establish a logical link between the signals of the rotary encoder and their control system.
Ö
It must not be possible for any person to be able to stand inside the safety device – or to enter it – while
the motor spindle is rotating.
Risk of fatal injury and damage to the product when operating without signals from the speed sensor
The speed signal must be generated from the installed sine/cosine encoder with two independent speed
signals. Otherwise, there is a risk of fatal injury and the possibility of causing damage to the motor spindle as a
result of over-revving.
►
Operate the motor spindle only if speed signals are available.
NOTICE:
For detailed information on the rotary encoder, refer to the third-party company instructions in Section
The installed rotary encoder generates a sine/cosine signal for rotating the spindle shaft. As a result, it is possible to
achieve high-resolution vector control of the motor spindle. When the spindle shaft is at a standstill, the rotary encoder does
not generate any signals.
Ö
Standstill monitoring
The transmitter wheel has a reference mark for the spindle shaft.
