Before Starting an Operation
6.3.1
Preliminary
checks
Mechanical specifications
Always be sure that the mechanical specifications such
as load torque, load inertia, accelera-
tion/deceleration times, operation speed, stopping accuracy, etc. are correct.
All
these points must be fully checked even if they seem to be complicated, in addition to providing
data for selecting the optimum motor.
Initial settings
Always be sure that each of the parameters in the drive unit and the PGU are compatible.
For instance, doublecheck
the mode of the position control pulse, logic polarity
of each signal,
rotating speed/direction of the motor, etc., or allowable pulse error (in-position), error judgment times,
etc.
Performing correct wiring
Since excessive voltage,
power terminal short-circuits in output wiring, etc. can result
in serious
accidents, always be sure to check these points carefully before turning ON the power supply.
