16.8.2

Parameter (No. 2092, Bit 0 of No. 8162) Write

Overview

This function allows you to write the following parameters using a PMC window function (function
instruction WINDW: SUB52) as long as a relevant axis is stopped. You can also use FOCAS2 or C
Language Executor to write parameters. The function can be used to write the following parameters:
-

Parameter No. 2092

Advanced preview feed forward coefficient

Bit 0 (SMR) of parameter No. 8162

Synchronous mirror-image control is:
0 :    Not applied. (The master and slave axes move in the same direction.)
1 :    Applied. (The master and slave axes move in opposite directions.)

This function can reduce the machining cycle time as it can write parameters without all of the axes
stopped.

Parameter

IPW

[Input type] Parameter input

[Data type] Bit

#7 IPW

The advanced preview feed-forward coefficient (parameter No. 2092) and bit 0 (SMR) of

parameter No. 8162 for specifying whether to apply a mirror image during
synchronization control are:
0:

Write-disabled during axis moving.

Write-enabled if the corresponding axis is stopped.

Limitation

Axis synchronous control

Under axis synchronous control, this function is disabled when slave axis parameter automatic setting is
enabled (bit 4 (SYP) of parameter No. 8303 = 1). (All the axes must be stopped before parameters can be
written.)

AI contour control

Under AI contour control, no parameter can be written even when the relevant axis is stopped.

16.8.3

Parameter (No. 1620) Write

Overview

This function allows you to write a time constant (parameter No. 1620) for rapid-traverse linear
acceleration/deceleration during axial movement. You can write the parameter using the PMC window
function (function instruction WINDW: SUB52), FOCAS2, or C Language Executor.
If you change the time constant during axial movement, the new setting take effect from the move
command encountered first after the axis stops. This function can reduce the machining cycle time as it
can change the time constant without all of the axes stopped.

Write-enabled.

Restrictions

- Axis of time constant 0

Do not use this function for an axis of time constant 0.

- Axis synchronous control

Note

NOTE

1 Set the time constants of the master and slave axes under axis synchronous

control to the same value.

2 Set the time constants of the master and slave axes under tandem control to the

same value.

WARNING

1 The safety related signal such as the protection door lock/unlock signal is

input(or output) to PMC/DCSPMC respectively and monitored in redundant
mode. If this transfer function is applied to the safety related signal, the
independence between PMC/DCSPMC is lost. Do not use this data transfer
function to control the safety related function.

2 The error of ladder program cannot be checked by safety function itself. The

confirmation of the safety related ladder program should be done enough by the
machine tool builder. The safety related ladder program should be guaranteed
by the machine tool builder.

KEY HIT STATUS SIGNAL OUTPUT FUNCTION

Overview

This function outputs the status of key hit to PMC signal when the soft key and MDI key are hit.

CAUTION

1 The delay from hitting key to outputting of PMC signal is 100ms or less.

Therefore, this function can not be used to operation that is required to quick key
response.

2 Only when a CNC hardware key is pushed, the PMC signal is output.
3 When CNC hardware key is pushed while using CNC screen display function

with PC connected by HSSB or Ethernet, the PMC signal is output.

4 On Stand-alone type CNC (Windows CE), when display and CNC are connected

by Ethernet, the PMC signal is not output.

5 This function is not available on NCGuide / NCGuidePro.

Explanation

Key hit status is output to PMC signal when soft key and MDI key are hit.
