TCMD4X(#5) The voltage of the TCMD signal output to the check board is:
0 : Unchanged (default)
1 : Multiplied by 4
Using these function bits changes the output ranges of the TCMD and
SPEED signals as listed in Table I (g) and Table I (h).
- TCMD signal output range

TCMD4X TCMD05 TCMD value/4.4 V Remark
0 1 Amplifier maximum current × 2 (A)
0 0 Amplifier maximum current (A) Conventional mode
1 1 Amplifier maximum current/2 (A)
1 0 Amplifier maximum current/4 (A) × 4 mode

* Letter P in the linear motor column has a different meaning
depending on the type of the scale.
• When the FANUC high-resolution serial conversion circuit is
used
(Incremental scale) → P = signal pitch[µm]
• When a scale that matches the FANUC serial interface is used.
(Absolute scale) → P = resolution [
µm] × 512
(9) Acquiring signals using a personal computer
Servo check boards A and B, listed in Table I (a), have a digital output
interface. Using the servo adjustment software (SD) enables them to
collect servo data such as position and speed through the interface into
a personal computer.
