acSmaxVelo (C, SSP)

Maximum spindle speed

Maximum spindle speed

This variable returns the maximum spindle speed for spindle mode.

This is formed from the smallest active speed limitation, and cannot be exceeded by speed programming or

override > 100%.

A speed limitation is indicated by the VDI interface signal DB31..,DBX83.1 'Setpoint speed limited'

and by $AC_SPIND_STATE, bit 10 (setpoint speed limited).

The cause of the speed limitation (machine, setting data, G code, VDI interface signal etc.) can also

be determined with the system variable $AC_SMAXVELO_INFO.

If the spindle is in axis mode, then the speed is not limited by $AC_SMAXVELO but instead the machine data

(MAX_AX_VELO, ...) typical for axis mode are active.

acSminVelo (C, SSP)

Minimum spindle speed

Minimum spindle speed

This variable returns the minimum spindle speed for speed control mode.

This is formed from the highest active speed increase, and cannot be undershot by speed programming

or override < 100%.

A speed increase is indicated by the VDI interface signal DB31..,DBX83.2 'Setpoint speed increased'

and by $AC_SPIND_STATE, bit 11 (setpoint speed increased).

The cause of the speed increase (machine, setting data, G code, VDI interface signal etc.)

can also be determined with the system variable $AC_SMINVELO_INFO.

If the spindle is in axis or positioning mode, then the speed is not increased by $AC_SMINVELO.

(machine, setting data, G code, VDI interface, etc.) as identifier/index.

The speed-limiting data can be determined with the index from the following table of existing

spindle speed limitations.

The system variable provides additional information about $AC_SMINVELO, and returns the speed increasing data

(machine, setting data) as identifier/index. The speed-increasing data can be determined with the index from the following

Active acceleration of the spindle

Active acceleration of the spindle

This variable returns the active acceleration of the spindle for spindle mode.

Bit 14 of $AC_SPIND_STATE (spindle accelerating) is set

for the duration of the acceleration to the defined setpoint speed.

Bit 15 of $AC_SPIND_STATE (spindle braking) is set

for the duration of the braking to the defined setpoint speed.

Apart from that, the acceleration-determining machine and setting data

can be determined with the system variable $AC_SMAXACC_INFO.

instead the machine data (MAX_AX_VELO, MAX_AX_ACCEL, ...) typical for axis mode are active.

and by $AC_SPIND_STATE, bit 10 (setpoint speed limited).

The cause of the speed limitation (machine, setting data, G code, VDI interface signal etc.) can also

be determined with the system variable $AC_SMAXVELO_INFO.

If the spindle is in axis mode, then the speed is not limited by $AC_SMAXVELO but instead the machine data

(MAX_AX_VELO, ...) typical for axis mode are active.

SSYNAC: Synchronous actions

OEM-MMC: LinkItem /Channel/SelectedFunctions/...

Several synchronous actions (M, H, S, E, F, T, D) can be active simultaneously in one channel. The module SSYNAC

contains a list of all the synchronous actions programmed in the current block. This module consists of arrays of

varying length because some types of synchronous actions might be programmed several times in a block. A

synchronous action that is not assigned produces a negative number for the respecitive index.

For each synchronous action there is an address variable and a variable in which the value of the address is entered.

5 M functions

3 S functions

3 H functions

1 T function

1 D function

6 F functions

1 E function

can be programmed in each part program block, but no more than 10 synchronous actions must be programmed

in a single block.

stringIsMeaning (C, Y)

Meaning of the string

As soon as PI _N_STRGIS is executed, the result from interpretation of the transferred string

is stored as a code in this variable. For example, the code for $P_TOOL is value 207.

Also refer to NC command STRINGIS.

Return value

000 = itemName string is unknown in the NCK

100 = itemName string is a language construct, but is not programmable (option/function is not

active)

2xx = itemName string is a permissible language construct (option/function is active)

2xx = is defined by:

200 = no interpretation possible

201 = DIN address / NC address (e.g. MEAS)

202 = G code (e.g. G04, INVCW)

203 = NC language function (= command with return value, parameter Passing) (e.g. GE-

TMDACT)

204 = NC language procedure (= command without return value, with parameter Passing) (e.g.

SBLOF)

205 = NC key word (e.g. DEFINE)

206 = machine/setting/option data (= parameter starting with $M / $S / $O)

207 = NC system parameter (= parameter starting with R and $)

208 = cycle name (name created by cycle)

209 = GUD variable (name created by GUD definitions

210 = macro name (name created by macro definition file)

211 = LUD variable (name created by active program)

212 = no Siemens G code, but an ISO G code

400 = NC address, which is not xx=01 or xx=10, and which is also not: G or R (e.g. T, D, F, H, L,

During NC operation different internal states occur and system-specific data may change during operation. To

distinguish those from system variables, they are classified as state data.

A distinction is made between:

- NCK-specific state data

- Mode-group-specific state data

- Channel-specific state data

- Drive-specific state data (FDD)

- Drive-specific state data (MSD)
