No. of encoder pulses
• Sets the No. of encoder pulses for 1
motor rotation.
(Ex) With 13-bit encoder: 8192 pulses =
2000 Hex
With 16-bit encoder: 65536 pulses =
10000 Hex
Note Selecting the motor model automati-
cally sets this parameter.
15 00
Encoder type
• Sets the encoder type.
0000 Hex: Incremental encoder
0100 Hex: Absolute encoder
Note Selecting the motor model automati-
cally sets this parameter.
Note Entering numerical value cannot
change this parameter.
15 00
Usage
• Sets the usage of an absolute encoder.
0000 Hex: Use it as an absolute encoder
0001 Hex: Use it as an incremental
encoder
Supplementary:
When using an absolute encoder as an
incremental encoder, the present position
does not show 0 at switching ON the MC
Unit. This is a normal condition because the
MC Unit is counting the initial incremental
pulses of the absolute encoder.
15 00
Motor rated speed
• Sets the motor rated speed.
Note Selecting the motor model automati-
cally sets this parameter.
Note Entering numerical value cannot
change this parameter.
15 00
Speed index
• Sets the unit system for the rated speed.
Note Make sure to set this parameter to
0000 Hex.
