îš• Coolant will be used more quickly when the TSC system is in use. Make sure to keep the coolant
level up and to check the level more frequently (check after every eight hour shift). Premature
wear of the pump can result from running with a low coolant level in the tank. The spindle
will shut off automatically if the coolant level gets too low.
îš• The maximum spindle speed when using the TSC system is 7500 RPM.
Note: Follow the tool manufacturer's instructions for speed and feed rate restrictions.
PROGRAM C OMMANDS
Through The Spindle Coolant is controlled mainly by two M Codes, M88 and M89; and four Parameters, 235,
236, 237 and 238 (See the "Parameters" section for a description of these). M88 is used to turn the system
on, and M89 is used to turn it off. The AUX CLNT button on the control panel may also be used to control TSC.
Pressing this button while in MDI mode will turn on the Through The Spindle Coolant system, and pressing it
again will shut off the system.
When Through The Spindle Coolant is on, the RESET and EMERGENCY STOP buttons on the control panel
perform slightly different functions. When RESET is pressed, the feed and spindle are shut off, as in a normal
reset. However, with TSC on, the control also waits for the spindle to stop, turns off the TSC coolant pump,
turns on purge, waits for [Parameter 237] turns off purge, and then turns off the precharge. When EMER-
GENCY STOP is pressed, the feed, spindle, and pump are shut off, as in a normal E-Stop. However, with TSC
turned on, the control will turn on purge air for the time specified in Parameter 237 so coolant can be purged,
and then shut off the precharge.
TSC PARAMETERS
The following parameters (and bits) apply only to the Through The Spindle Coolant system:
WARNING!
These are factory preset parameters. Changing them may void the
warranty.
Parameter 235 TSC PISTON SEAT
Parameter 236 TSC LOW PR FLT
Parameter 237 TSC CLNT LINE PURGE
This can be increased by the machine user if desired to help purge coolant from small orifice tooling. The
minimum setting is 2500 milliseconds.
Parameter 238 MAX TSC SPINDLE RPM
Parameter 209 COMMON SWITCH 2
The bit, "TSC ENABLE" in Parameter 209, is set to "1".
Parameter 278 COMMON SWITCH 3
The bit, "TSC PRG ENBL" in Parameter 278, is set to "1".
A complete description of TSC parameters is given in the "Parameters" section of this manual.
