#3: Increase spindle speed >>
UPGMTURN is designed for spindle control with 4 speed stages. These are either selec-
ted from the part program by means of M41, M42, M43, M44 or set via manual speed se-
lection on the MCP using the customer keys #1 or #3. (Detailled description in Section 5.1
“Description of the Logics”)
S #2: Spindle jog mode (only in JOG mode)
The spindle rotates with direction of rotation M3 and smallest speed. This function can only
be activated in JOG mode.
S #4: Manual tool change (only JOG mode)
Press the #4 key as long as the toolholder has reached the desired position. When you
release the key, the UPGMTURN automatically starts the retraction clamping process.
When you press #4 for a short time, the toolholder is moved by one position further and is
clamped. The time for the retraction clamping process is set in the PLC machine data.
S #5: Manually initiated lubrication process
When you press the #5 key, the output signal for lubrication is activated for one interval
(set in the PLC machine data).
S #6: Coolant ON/OFF (toggle key, only in JOG mode)
S #16: Reset alarm output
After the alarm source has been removed, the alarm output (O0.7) can be deactivated by
pressing #16 (acknowledge alarm).
Description of the output signals
S O0.0 Control contact Spindle CW (direction of rotation M3)
S O0.1 Control contact Spindle CCW (direction of rotation M4)
S O0.2 Spindle brake active for one interval (set in the PLC machine data)
If spindles with only one direction of rotation are used, output O0.1 must be masked.
S O1.0, O1.1, O1.2, O1.3: Control signals - spindle speed stages
M41 M42 M43 M44
O1.0 n n
O1.1 n n
O1.2 n n
O1.3 n n
These signals can be used either for selecting the speed stage of 2-stage a.c. motors and/
or switching the gear.
1. If a 1-stage a.c. motor is used as the spindle drive, O1.0, O1.1, O1.2, O1.3 must be
masked.
2. If a 2-stage a.c. motor is used as the spindle drive, only O1.0, O1.1 are used, and O1.2,
O1.3 must be masked.
S O1.4, O1.5, O1.6, O1.7:
Display of spindle speed stages (can be masked out if not needed).
