5.5 Precautions
5.5.1 When you use SANYO DENKI servo amplifier with other
manufacturer linear motor combined.
■
When you use our servo amplifier with other manufacturer linear motor combined, we provide
“
servo amplifier parameter (motor parameter file)
”
needed to drive the motor based on motor
constants you provide to us. In this case, we do not conduct any combination tests of servo
amplifier and the linear motor, so we assume no responsibility whatsoever for any
combination operations and characteristics of the motor. In addition, we assume no
responsibility whatsoever for any failures caused by the linear motor.
5.5.2 Setting of parameters to combine amplifier and motor
■
Set "motor parameter" for the liner motor you use.
■
Maximum moving rate shall be limited by resolution of the linear encoder you use. When
using linear motor at maximum moving rate, set the value of minimum pulse width or less to
Index 0x20F1-2 "motor incremental encoder digital filter setting value: [ENFIL]". (factory
setting is default set value [minimum pulse width =220nsec])
■
When connection of phase sequence or polarity of motor power line, linear encoder signal line,
and hall sensor signal line (when you use) is not correct, there may be at a risk of loss of
control. Perform wiring so that the relation between each phase of voltage induced by motor
and each signal shall be as indicated in the figure below when moving linear motor in the
direction of leading out a power line from linear motor core.
