Explanation
• Specifies the external input signal for each function at a latch request.
Bit
00 to 07 X: Specifies the latch input signal for LATCH command (Present
position latch).
08 to 31 Reserved
• Setting range: 00 to 03 Hex (0 to 3)
00 Hex (0): Phase-Z (Phase-C) signal is used as the latch request signal.
01 Hex (1): External input signal 1 is used as the latch request signal.
02 Hex (2): External input signal 2 is used as the latch request signal.
03 Hex (3): External input signal 3 is used as the latch request signal.
To set this parameter, the input terminal has to be enabled in the servo
parameter Pn511.
(It is allocated according to the initial setting; however, it will require special
attention when the user has customized the setting of the parameter.)
This section explains the concept of the gear ratio.
In case of position command:
In a machine configuration where the motor axis rotation (m) results in the
machine axis rotation (n), set the gear ratio as shown below:
[P5AA05: Gear ratio 1 (Motor rotation speed)] = m
[P5AA06: Gear ratio 2 (Machine rotation speed) = n
Example)
If P5AA05 = 2 and P5AA06 = 1, giving a command to rotate the machine axis
at 1000r/min will make the motor axis rotate at 2000r/min.
In cases of Speed Command and Torque Command:
Only the SPEED and TORQUE commands can control speed and torque
respectively. These commands are for the motor axes, so there is no need to
set the gear ratio.
Example)
Even when P5AA05 = 2 and P5AA06 = 1 are set, giving a command to rotate
at 1000r/min with the SPEED command will make the motor axis rotate at
1000r/min.
