2) Then make clear the level of servo driver alarm output port when there is no alarm. If it is normally
low-level, the input port polarity of servo alarm should be
―P‖ in ―IOPorts‖ window of software; if it is
low-level when alarm occurs, the port polarity should be
―N‖; for polarity setting, refer to Ports
Detection part;
3) Make sure the type of pulse signal received in
parameters setting of servo driver is ―pulse +
direction‖; make clear whether there is external emergency stop signal input in the input terminal
of servo driver, and the logic of this signal;
4) Before the trial run of the driver, 24V power supply must be provided for the terminal board,
because the 24V power for the driver is indirectly provided through the terminal board; if the driver
can
‘t rotate, make sure the driver parameter ―forward and reverse rotation input prohibited‖ is set
invalid.
5.4. System Parameter Settings
5.4.1. Pulse Equivalent Setting
Select [System Parameters] under [Mach] menu to eject
―System Parameter‖ window, then click
[Manufacturer] button and find the parameter [Pulse equivalent] of the two axes. The password of
manufacturer parameters
is ―ncstudio‖. The smaller the pulse equivalent is, the higher the resolution
will be. The value of pulse equivalent will affect the maximum feed speed. Generally speaking,
regarding the pulse equivalent of mold machines, 0.001mm/p (the corresponding maximum feed rate
is 9600mm/min) or 0.0005mm/p (the corresponding maximum feed rate is 4800mm/min) can be taken
into consideration; for users who are not very critical of the accuracy, the pulse equivalent can be set a
litter larger, such as 0.002mm/p (the corresponding maximum feed rate is 19200mm/min) or
0.005mm/p (the corresponding max. feed rate is 48000mm/min). When pulse equivalent is confirmed,
calculate the electronic gear ratio of servo driver in terms of value of pulse equivalent. Please refer to
Chapter 5.7 for the calculation of electronic gear ratio.
5.4.2. Axis Direction Setting
Move the machine tool manually to make sure the correctness of moving direction of each axis. Note
that NcEditor adopts
―right hand‖ coordinates system. For X-axis, right movement is the positive
direction; while the positive direction of Y-axis is to move away from the operator (if the movement of
Y-axis is the movement of worktable, the positive direction is the worktable moving towards the
operator). If the direction is not correct, alter the manufacturer parameter
―Axis direction‖ from 1 to -1
(or -1 to 1) or the relative parameters of servo driver.
