(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.

5-2 Spindle control signal
The sequence input/output signals exchanged between the NC and spindle drive unit are explained in
this section. The status of each signal is displayed on the NC SPINDLE MONITOR screen.

Spindle control input 1
bit0. READY ON command (RDY)
This signal is input when preparations to rotate the motor are completed. The forward run and
reverse run commands will not be accept ed even if input before this signal turns ON.
bit1. Servo ON command (SRV)
This is input for position control, excluding orientation. If this signal is not ON, position control will
not be executed even if the spindle control mode selection command's combination indicates the
position control mode.
bit6. Parameter conversion command (PRM)
This is started when the spindle parameters are converted on the NC screen.
bit7. Drive unit alarm reset command (ALMR)
This turns ON while NC reset is input. Spindle alarms that can be reset with NR are reset.

5 - 7
bit8. Torque limit 1 (TL1)
bit9. Torque limit 2 (TL2)
bitA. Torque limit 3 (TL3)
This signal is used to temp orarily 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.

SP054 TLM7 Torque limit 7 Set the torque limit rate for the torque limit signal 111. 0 to 120(%) 70
bitB. Pole position check command (MAC) (only for MDS-C1-SPM)
When requesting pole position che ck from NC, pole position check is performed by turning ON this
signal. However, the pole position check is not performed when the check has already completed
(control output 1/bitB=1). When SP207≠0 is set, it stars automatically on the spindle drive unit side.
bitF. Cutting (G1)
This signal is used to determine whether cutting is taking place or not during C-axis cont rol.
