(3) Control signal output (Data No. 80 to 87)
A hexadecimal display is converted into a decimal and output. The method of calculating the
magnification is the same as (2). The status cannot be output for each bit, so output the status for
all 16 bits.
(Example) Orientation indexing control
With orientation indexing control, the following operations of the "Control output 4" can be
observed as shown on the right:
bit4: Orientation completed
bit7: Indexing positioning completed
Note that the weight of the D/A output differs for each bit.

4-2 Spindle control signal
The sequence input/output signals of the spindle drive unit are explained in this section. The status of
each signal is displayed on the spindle monitor of the personal computer when the personal computer
is connected.

Spindle control input 1
bit0. READY ON command (RDY)
1) This signal is input when the motor is ready to rotate. This is valid when the circuit between 1 pin
(REDY) and 19 pin (CES1) of CN10 is closed (ON). When this signal is turned ON, the main
circuit of the converter unit will be turned ON.
2) Before this signal is turned ON or within approx. one second from when this signal is turne d ON
till the "in READY ON" signal is turned ON, signals are not accepted even if turning the
forward/reverse run command, orie ntation command ON.
3) If this signal is turned OFF during motor rotation, the current to the motor is shut OFF and the
motor will coast to stop.
4) Turn this signal OFF for safety before the operator touches the spindle directly and
attaches/removes the workpiece or tools. However, be careful not to turn this signal ON/OFF
too frequently (100 times or more/day).
bit6. Parameter conversion command (PRM)
This is started when the spindle parameters are converted on the personal computer screen.
bit7. Drive unit alarm reset command (ALMR)
This turns ON while the alarm reset is input. Spindle alarms are reset.
However, if this signal is turned ON during the motor rotation, the power supplied to the motor is
shut off and the motor will coast to stop.

bit8. Torque limit 1 (TL1)
bit9. Torque limit 2 (TL2)
bitA. Torque limit 3 (TL3)
This signal is used to temporarily reduce the spindle motor's output torque such as when clamping
the spindle motor on the machine side. The torque limit is designated in percentage using the
motor's short-time rating as 100%.
Set the SP021, SP049 to SP054 torque limit value with a combination of TL1 to 3.
