TE1: Clearance control - 840D sl only

15.5 Startup

15.5 Startup
Compile cycle
Before commissioning the technological function, ensure that the corresponding compile cycle
has been loaded and activated (see Section "TE01: Installation and activation of loadable
compile cycles (Page 549)").
15.5.1

Activating the technological function

The technological function is activated via the machine data:
MD60940 $MN_CC_ACTIVE_IN_CHAN_CLC[0], bit n = 1
n = channel number - 1; bit0 = channel 1, bit1 = channel 2, etc.
Note
The technological function can be activated for several channels simultaneously.
15.5.2

Configuring the memory

The technological function requires additional data in the NCK-internal block memory. The
values must be increased for the following memory configuring channel-specific machine data:
● MD28090 $MC_MM_NUM_CC_BLOCK_ELEMENTS += 4 (number of block elements for
compile cycles)
● MD28100 $MN_MM_NUM_CC_BLOCK_USER_MEM += 20 (size of block memory for
compile cycles (DRAM) in KB)
15.5.3

Parameter settings for input signals (840D sl)

The following input signals must be parameterized in the machine data:
● Clearance sensor input voltage
– 1 analog input
● "Sensor collision" input signal (optional)
– 1 digital input
