Note When using models with the previous specifications, take appropriate coun-
termeasures against dropping in the vertical axis.
Specifications after Change
Brake output and RUN command output are turned OFF when the driver
alarm input signal is received. (Operation when other errors that result in an
emergency stop are generated will be the same as for previous models.)
Encoder ABS/INC This parameter specifies whether the encoder being used is an absolute or
incremental encoder. Set the parameter to “Absolute encoder for U or W
series” when using an absolute encoder with a U-series Servo Driver.
Encoder Resolution This parameter sets the encoder resolution. Encoder resolution is the number
of pulses (encoder frequency dividing ratio) that can be output per encoder
revolution. It can be set from 1 to 65,535 and the default setting is 1,000 pr.
Make sure the resolution satisfies the following condition.
Upper limit of max. motor speed [r/min]
≤
500 [kp/s] x 60
÷
encoder resolution [p/r]
If the resolution does not satisfy the above condition, reduce the resolution
from parameters at the servo driver or reduce the maximum number of motor
revolutions.
When using a G-series Servo Driver, set the encoder resolution to the same
value as Pn44 (Encoder Divider Numerator Setting), and set Pn45 (Encoder
Divider Denominator Setting) to 0.
Encoder Ratio This parameters specifies the encoder ratio (4, 2 or 1). The default setting is a
ratio of 4.
