5 Calibration
5.1 Introduction / When to calibrate
General
This chapter includes general information and detailed procedures about the
calibration methods: The fine calibration and the update of the revolution counters.
When to perform a fine calibration
The fine calibration of the FlexPLP must be done at the first commissioning or after
the replacement of mechanical parts such as:
A Ø8 x 50 mm pin is required to perform the fine calibration.
When to update the revolution counters
The FlexPLP axis must be calibrated each time the contents of the revolution
counter are changed or lost. This will occur when:
The revolution counters must also be updated after the device and controller are
connected at the first installation.
Power failure
There's no need to calibrate the FlexPLP after a power failure, the backup battery
included in the SMB box will store the resolver position until power is restored.
Precautions
Product manual - FlexPLP IRPLP 220
3HAW050041018-001 Revision: C
•
Servomotor
•
driving belt/pulley or gear/rack
•
Ballscrew
•
Replacement of a complete axis
•
The battery is discharged
•
A resolver error occurs
•
The signal between a resolver and measurement board is interrupted (e.g.,
cable disconnected)
•
A FlexPLP axis is moved with the control system disconnected
CAUTION
•
If an axis is incorrectly calibrated or if the revolution counter is incorrectly
updated, it will cause incorrect positioning, which in turn may cause damage
or injury! Check the calibration position very carefully after each update.
•
Before any service work, make sure that nobody stands near the mechanical
unit when the carriage moves, and make sure that no object which could
get in the way of the carriage or jam between the carriage and the covers.
