2. Safe operation
2.1 Hardware overtravel protection
The overtravel protection is the necessary measure for the machine tool to prevent damage caused
when the X axis and Z axis exceed the travel. The hardware overtravel protection function is enabled
and controlled by system parameter 22 --- hard limit, which is enabled if the parameter is set to “1”.
The effective level of hardware limit is controlled by system parameter 23 --- effective level of hard
limit. Set the above two parameters according to the actual connection of the machine tool to realize
overtravel protection. Install travel limit switch in the position of maximum travel in positive and
negative directions of axis X and axis Z respectively, and connect the wires according to the figure
below. When overtravel occurs, the travel limit switch acts, and the system stops moving and displays
the alarm of not ready. It indicates that the hard limit enable control parameter can only control the
limit function of motion chip, and the limit response of the motion chip features high speed and low
delay. The hard limit function is still valid in this system when the hard limit parameter is disabled.
The software will execute the limit function instead. Comparing with the limit by the chip, the delay is
increased, but the immunity is much better.

2.2 Software overtravel protection
The software limit function is enabled and controlled by system parameters --- software limit,
which is enabled if the parameter is set to “1” and disabled if set to “0”.
The software travel range is set by system parameters: positive soft limit in X axis, negative soft
limit in X axis, positive soft limit in Z axis and negative soft limit in Z axis, and refers to the
coordinates of the machine tool. As shown in the figure below, X and Z are two axes of the
coordinates of the machine tool, 25 and 26 are the maximum travels of X axis in positive and negative
directions, 27 and 28 are the maximum travels of Z axis in positive and negative directions, and the
area inside the dashed frame is the range of software travel.

Installation precautions
Installation condition of electric cabinet
When design the electric cabinet, the distance between the rear cover and the case should be at least
20cm. It should be noted that the temperature difference between the inside and outside of the cabinet
shouldn’t exceed 10℃ when the temperature inside the electric cabinet rises.
The electric cabinet should be able to prevent the entering of dust, cooling liquid and organic solution.
The electric cabinet should be equipped with fan to ensure internal air circulation.
The display panel should be installed at the place that the cooling liquid can’t spray on.

Switching power supply
When design the electric cabinet, please reduce the external electrical interference to avoid affecting the
system.
To avoid interference
When the system is designed, we have taken measures to shield space electromagnetism radiation,
absorb impact current, filter power clutter and other measures to avoid interference. It can prevent
the external interference to the system to a certain extent. To ensure that the system works stably,
please take the following measures when install the system:
1: Keep the machine tool away from equipment that may cause interference (e.g. frequency inverter, AC
contactor, static generator, high voltage generator and section device of power lines). At the same time,
connect the switching power supply to the filter separately to improve the interference resistance of the
machine tool (see Fig. 1-4).
2: To supply power for the system through isolation transformer, the machine tool installed with the
system should be grounded, and machine tool and the drive should be connected to separate earth wire
from the connection point.
3: Interference suppression: connect RC loop in parallel on both ends of AC coil (0.01μF, 100~200Ω, as
in Fig. 1-5); approach to inductive load when install RC loop; install reverse parallel freewheeling diode
on both ends of DC coil (Fig. 1-6); connect surge absorber in parallel at the winding end of the AC
motor (Fig. 1-7).

13.1.1 CONNECTION OF MOTOR, DRIVE AND CONTROLLER
Since there are many types of drives, the definitions of interfaces are different, but they all have direction signal cables
and pulse signal cables, as well as the control signal and drive enabling signal. Many drives don’t have this signal, and
it is possible to select the enabling mode by setting the drive parameters for some drives. The wiring mode of pulse
output signals:
1. Differential mode:
This mode is suitable for step drives with independent pulse and direction input and most servo drives. Use this
mode to get better anti-interference.
Step motor drive
Servo motor drive
Note: Never connect any two of PU+, PU-, DR+ and DR-; otherwise, the pulse interface will be damaged.
2. Single end mode:
This mode is suitable for the step drives that the anodes of pulse and direction are connected together.
Step motor drive
Note: It isn’t suitable for the step drives that the cathodes of pulse and direction are connected together.
Certain drives connect the anodes of optical coupling input, i.e. the common anode connection. At this moment,
connect the wires according to the figure below and do not connect PU+ and DR+ together; otherwise, the pulse
interface will be damaged.
The common cathode connection, i.e. connecting the cathodes of optical coupling input together, isn’t suitable
for machine tool controller.
Please note that the PU_COM is only for the non-differential connection of the drive pulse; otherwise, the
controller will be damaged.

13.1.2 SETTING AND CALCULATION OF ELETRONIC GEAR
RATIO
After connection, check again according to the wiring diagram. If the connection is proper, check the rated working
voltage of the drive (this procedure is easy to be neglected, and thus cause severe damage and delay the test). If the
supply voltage accords with the rated voltage, please set the drive in this method: First, set the parameters of the drive
according to the rated parameters of the motor, such as rated rotation, torque and current. The objective of the test is to
make the motor drives the work piece moving in specified instructions. We would like to introduce a new term,
electronic gear ratio (similar to functional mechanical gearbox). Because the motors and mechanical transmission ratios
are different, the unit pulse movements are different; therefore, it is necessary to select specific transmission ratio and
motor during machinery manufacturing. The electronic gear ratio has solved this problem. The minimum instruction
unit of this system is 0.001mm. A calculation formula follows:
Motion distance of every rotation mm*1000 Gear at motor end
CMR: Instruction magnification coefficient (system parameter 1 and 3)
CMD: Instruction frequency division coefficient (system parameter 2 and 4)
The movement of every rotation is the lead of the screw
Gears at screw end (indirect connection, has rotation ration)
64
Gears at motor end (indirect connection, has rotation ration)
If 403BM two-phase step drive and 56 two-phase motor, the screw lead is 4mm and the direct connection
transmission ratio is 1:1
It is known from the manual of 403BM drive that the base working voltage is DC40V, and six coefficients are
2, 4, 8, 16, 32 and 64 respectively. The working current of the motor can be set. The step distance is 1.8° and
the rated current is 3A. The drive uses 32 subdivisions and the current is set to 3A, and the electronic gear
PDF 文件使用 "pdfFactory Pro" 试用版本创建 ÿ www.fineprint.com.cn
CNC4220 Machine Tool Operation and Test
ratio is 200*32/4*1000=7/5; and CMR=7, CMD=5.
If the numerator of the electronic gear ratio is larger than the denominator, the top speed that the system allows will
drop.
If the numerator of the electronic gear ratio isn’t equal to the denominator, the positioning accuracy of the system will
drop.
To ensure the positioning accuracy and speed index of the system, if the digital servo with electronic gear ratio
function is equipped, please set the electronic gear ratio to 1:1 and set the calculated electronic gear ratio into the
digital servo.
If step drive is equipped, please use the drives that have step subdivision function, select reasonable mechanical
transmission ratio, and set the electronic gear ratio of the system to 1:1 to avoid significant difference between the
numerator and denominator of the electronic gear ratio.
13.1.3 ACCELERATION/DECELERATION FEATURES
ADJUSTMENT
Adjust the system parameters according to the features of the drive and motor, as well as the load of the machine
tool:
System parameters 10, 11: quick moving speed of axis X and axis Z;
System parameters 14, 15: linear acceleration/deceleration time constant when axis X and axis Z are moving in high
speed;
System parameter 7: acceleration/deceleration time constant of cutting feeding and manual feeding;
System parameter 6: Start/stop speed of acceleration/deceleration of cutting feeding;
The larger the acceleration/deceleration time constant is, the slower the acceleration/deceleration is, the lower the
impact of machine tool movement is and the lower the processing efficiency is; the smaller the
acceleration/deceleration time constant is, the faster the acceleration/deceleration is, the higher the impact of machine
tool movement is and the higher the processing efficiency is.
If the time constants of acceleration and deceleration are same, the higher the start/stop speed of the
acceleration/deceleration is, the faster the acceleration/deceleration is, the higher the impact of machine tool movement
is and the higher the processing efficiency is; the lower the start/stop speed of the acceleration/deceleration is, the
slower the acceleration/deceleration is, the lower the impact of machine tool movement is and the lower the processing
efficiency is.
The principle of acceleration/deceleration features adjustment is to reduce the acceleration/deceleration time constant
and increase the start/stop speed of the acceleration/deceleration properly to improve the processing efficiency on the
premise that the drive doesn’t alarm, the motor doesn’t desynchronize and the machine tool movement doesn’t have
obvious impact. If the time constant of the acceleration/deceleration is too low, or the start/stop speed of the
acceleration/deceleration is too high, it is easy to cause drive alarm, motor desynchronization or machine tool vibration.
When the matched step motor drives the device, if the quick moving speed is too high, acceleration/ deceleration time
constant is too low, and the start/stop speed of acceleration/deceleration is too high, the motor may be desynchronized.
If AC servo drive devices are equipped, please set the start/stop speed to a high value and set the acceleration/
deceleration time constant to a low value to improve the processing efficiency. To get the perfect acceleration/
deceleration features, please set the acceleration/ deceleration time constant to 0 and adjust the acceleration/
deceleration parameters of the AC servo.
Acceleration/deceleration control
System parameter 10: quick moving speed of axis X (unit: mm/min)
System parameter 11: quick moving speed of axis Z (unit: mm/min)
System parameter 14, 15: linear acceleration/ deceleration time constant when axis X and axis Z are moving in high
speed
System parameter 9: top cutting feeding speed of axis X and axis Z (unit: mm/min)
System parameter 7: feeding acceleration time constant; if this value is 0, no acceleration is performed (unit: ms)
System parameter 6: start speed of acceleration and stop speed of deceleration during cutting feeding (unit: mm/min)
13.1.4 TROUBLESHOOTING FOR MOTOR DRIVE
I. The motor doesn’t work, or stops soon, and accompanied with hum.
Analysis: The reasons may be:
A. The power supply or wiring of the motor has problem, for example, the pulse cable isn’t connected properly. The
drive enabling signal isn’t connected properly.
B. The drive parameter setting has problem, such as the control mode (in position control mode), motor enabling mode,
etc.
C. The motor stops soon and hums. The machine tool controller is still working normally, the coordinates still change
according to the program instructions, this is because that the step motor and its load have inertia, and thus the motor

can’t start and stop immediately during working, loses steps when it is started and exceeds steps when it is stopped. To
solve the problem: through an acceleration and deceleration process, start with low speed, accelerate to a certain speed
and then decelerate until stopped. The reasonable and smooth acceleration/deceleration control is the key to ensure the
reliable, efficient and accurate running of the step driving system.
First, check whether the power supply of the drive is normal, and then check whether all the cables of the drive are
connected. Refer to the drive instructions to check whether it is necessary to connect enabling signal. If yes, please
follow the instructions (the drive interface of the system doesn’t have dedicated enabling port, but 24V and 5V DC
voltages are available). Then, check whether the working mode of the drive is position control mode and direction +
pulse mode. Please select internal power enabling mode if servo is used. If the motor desynchronizes, please modify
the start speed, quick moving, feeding speed, maximum feeding speed and acceleration time of axis X and axis Z.
II. The motor only runs in one direction
Analysis: This is because the direction signal can’t be changed. Please check whether the direction signal DR is
connected normally.
Method: Measure the DR+ and DR- voltage signals with a voltmeter and then press the positive/negative movement
key of the axis, and the polarity of the voltage shall change. If the polarity doesn’t change, the system has fault. Please
contact the system manufacturer. If the polarity changes, the drive has fault.
III. Drive alarm
Please refer to the drive instructions to check the alarm reason, eliminate the fault and clear the alarm (the system drive
has a drive alarm reset signal and you can press the Reset key to clear)
13.2. Hard limit function
The hard limit function consists of two hard limit travel switches, which are positive limit and negative limit.
Digital input wiring board
XS5 interface
xis Z negative limit travel switch
Axis X positive limit travel switch
xis X negative limit travel switch
13.2.1 ENABLING HARD LIMIT FUNCTION
The hard limit function is controlled by system parameters. Set the system parameter 22 hard limit enabling to “1” to
enable the hard limit function, or set to “0” to disable the function. The system parameter 23 is hard limit effective level.
Set the value (NO: 0, NC: 1) according to the actually connected switch type (NO, NC). After setting the hard limit
parameters, move to the limit switch of every axis in low speed manually and check whether the parameters are set
properly.
To move to the positive limit switch of axis X, when the positive limit switch is enabled, axis X stops moving
immediately and alarms, and won’t move to the positive direction. To solve the problem, move to reverse direction to
leave the limit switch, and press the Reset key to clear the alarm.

13.2.2 TROUBLESHOOTING FOR HARD LIMIT
A. Hard limit function is invalid: please check the system parameters ---- whether the hard limit enabling is set to 1; if it
is 0, please select 1 to enable the hard limit function.
B. The limit of certain directions is invalid; the limit in one of the four directions is invalid. This means that the
parameter settings are proper. Please check whether the cables in the invalid direction are connected and whether the
switch is damaged. Please note that the hard limit levels of axis X and axis Z are set by two parameters separately, and
thus the limit switches of same axis shall be in same type (NO or NC). Check whether the limit switch is connected.
For your safety, please enable the hard limit function, move the axes to the center position manually and then switch to
MDI mode. Switch to the input point interface, press the limit switch of every axis with hands, and the controller sends
alarm tone. If there is no change, please check the corresponding external wiring. If the external wiring is proper, please
check whether the machine tool input port is damaged. If yes, contact the system manufacturer.
13.3. Mechanical origin adjustment
As connected in the figure below:

Adjust the parameters according to the effective level of connection signal, origin mode and direction:
13.3.1 ORIGIN PARAMETER SETTING
System parameter 32: Origin mode

=1: Single switch returns to mechanical origin
=2: Deceleration switch and servo origin return to mechanical origin
System parameter 33, 34: effective level of deceleration signal when return to mechanical origin

= 1: effective when disconnected from 0V
= 0: effective when connected to 0V
System parameter 41, 42: axis X and axis Z return to reference coordinates
System parameter 35, 36: select positive or negative for the origin direction of axis X and axis Z
System parameter 37, 38: high speed when axis X and axis Z return to origin
System parameter 39, 40: low speed when axis X and axis Z return to mechanical origin
After confirmed that the hard limit function and origin signal are effective, it is possible to
perform the mechanical origin operation.
Check whether the origin switch is connected properly. For your safety, please move the axes to the center position
manually and then switch to MDI mode. Switch to the input point interface, press the origin switch of every axis
with hands, and the controller sends alarm tone. If there is no change, please check the corresponding external wiring.
If the external wiring is proper, please check whether the machine tool input port is damaged. If yes, contact the
system manufacturer. Perform the origin operation if the input signal is correct.
Generally, the mechanical origin is installed at the position of maximum travel. The effective travel
of the origin block is at least 25mm. To ensure the accurate origin, please ensure sufficient
deceleration distance, so that the speed can be reduced. The higher the mechanical origin speed is, the
longer the origin block is. Otherwise, the origin accuracy will be affected because the system
acceleration/deceleration and machine tool inertia make the mobile extension units cross the origin
block and no sufficient deceleration distance is reserved.
The diagram that uses one approach switch as the deceleration and origin signal at the same time
follows:

D: If no servo origin signal is detected, it runs reversely in fixed low speed, and starts checking
the servo origin signal (DEC). When it detects the servo origin signal for the second time, the origin
signal is valid, the movement stops and the mechanical origin operation completes.
13.3.2 TROUBLESHOOTING FOR MECHANICAL ORIGIN
A. The origin direction is reversed: the parameter of origin direction is reversed; please modify
the parameter.
B. The motor desynchronizes in the origin process: the origin speed is too high; please change it
to appropriate value.
C. Overtravel occurs in the origin process: the origin switch is invalid; please check whether the
origin switch and wiring are normal
13.4. Reverse clearance compensation
Measure with dial indicator, dial gauge or laser detector. The reverse clearance should be
compensated accurately to improve the processing accuracy. Therefore, it isn’t recommended to
measure the reverse clearance of screw in handwheel or single step mode. Please measure the
reverse clearance in the method below:

encoder test interface in the diagnosis interface. Rotate the main axis manually, the main axis encoder
counter takes count in normal condition, and the stats of phase A and phase B flash. If there is no change,
please check whether the power supply of the encoder interface is normal. If yes, check the differential
output signal of phase A and phase B. During low speed rotation, the voltage changes a little. If the
power supply is normal and the driving voltages of phase A and phase B change, the input port of
machine tool may be damaged. Please contact the system manufacturer.

Main axis control mode (system parameter 58)
Multi-section speed control mode
Two modes are available:
A: Four sections direct output
B: BCD coding output (16-section speed)
Stepless speed regulation mode: analog voltage control mode
If the parameter value of main axis control mode is set to 0, it is controlled by four-section speed. If the
value is set to 1, it is the stepless speed regulation controlled by analog quantity. If the value is 2, it is
controlled by 16-section speed. If the value is 3 (DC drive main axis motor stepless speed regulation
mode), M03 output terminal controls the positive/negative rotation of main DC motor (if the logical state
is 0, the main axis rotates forwardly; if the logical state is 1, the main axis rotates reversely) and M04
terminal controls the start and stop of main axis. To make the motor rotate, give start signal to the signal
in specified direction. If the output logic of M04 terminal is 1, the main axis is started; if it is 0, the main
axis is stopped. See the table below for the control logic

shadow part is the chuck clamping time and controlled by the parameters. The output time sequence is
shown in the figure below.

Chuck mode “0”: continuous output control mode of internal chuck; chuck mode “1”: continuous output

The difference between “0” and “2” of chuck clamping settings: if “2” is selected, main axis and chuck
are interlocked.
If the chuck clamping setting is “1”, check the clamping in position signal. The principle of the four
working mode follows:
Chuck mode 0: while executing clamping instruction M12, open XS6-12 port and close XS6-13 port,
and check the clamping in position signal pin XS5-8. If the clamping signal is detected in the clamping
time of the chuck, the M12 instruction is executed; otherwise, send alarm info “chuck clamping
overtime”.
Chuck mode 1: while executing clamping instruction M12, open XS6-13 port and close XS6-12 port,
and check the clamping in position signal pin XS5-7. If the clamping signal is detected in the clamping
time of the chuck, the M12 instruction is executed; otherwise, send alarm info “chuck clamping
overtime”.
Chuck mode 2: while executing clamping instruction M12, open XS6-12 port and close XS6-13 port,
delay chuck clamping time and then clock the XS6-12 port, and check the clamping in position signal
pin XS5-8. If the signal is valid, the M12 instruction is executed; otherwise, send alarm info “chuck
clamping overtime”.
Chuck mode 3: while executing clamping instruction M12, open XS6-13 port and close XS6-12 port,
delay chuck clamping time and then clock the XS6-13 port, and check the clamping in position signal
pin XS5-7. If the signal is valid, the M12 instruction is executed; otherwise, send alarm info “chuck
clamping overtime”.
Note: when check the chuck clamping parameter settings: 0- do not check, do not interlock with
main axis, 1- check the clamping signal and interlock with main axis, 2- do not check the clamping
signal but interlock with main axis, 3- check the clamping signal but do not interlock with main
axis
13.8.3 TROUBLESHOOTING FOR CHUCK CONTROL

A. No. 46 system knives – Knife station (knife position) number for mechanical turret. Please select “0”
for line knife structure.
B. No. 47 knife position signal level – the effective level of knife position sensor when the knife is in
position
C. No. 48 knife rack lock level – select knife in positive rotation and lock in reverse rotation; the
effective level of lock sensor
D. No. 49 maximum knife replacing time – the time that normal knife rack rotates one circle
E. No. 50 lock delay time – the delay time from the completion of knife selection in positive rotation to
the start of reverse lock
F. No. 51 knife rack reverse lock time – the time required to lock the knife rack
Note: the above parameters are effective to electric knife rack and the line knife doesn’t require the
setting.

13.10.3 TROUBLESHOOTING FOR KNIFE REPLACING
When the system uses electric turret knife rack, the knife replacing will fail if the parameter setting isn’t
proper, for example, can’t replace the knife. Please check whether the knife number is set to 0, whether
the maximum knife replacing time is reasonable, and whether the settings of connection and jumper of
knife rack signal conversion board are proper. These settings can be checked in the diagnosis interface.
Please reduce the range to eliminate the fault.

13.11.4 PRECAUTIONS AND PARAMETER SETTING FOR
HANDHELD BOX
The handheld box and additional panel share the interface XS7, and thus they can use only one function
at the same time. Select the handheld box or additional panel through system parameter 86: if parameter
86 = 0, the handheld box is selected; if parameter 86 = 1, the additional panel is selected.
The output signals of handheld box and additional panel have corresponding diagnosis signals on the
controller, as in the figure below
Main axis encoder
Handwheel
Main axis encoder test
Handheld box test
13.11.5 TROUBLESHOOTING FOR HANDHELD BOX
When any fault occurs, please set the operation mode to MDI, press the Diagnosis key to enter the
diagnosis interface, and press the Up/Down key to switch to handheld box test interface, as in the figure
above. Then, rotate and press the corresponding switch, and the corresponding diagnosis signal changes;
otherwise, this signal has fault. Please check the connection of the signal wire and the switch. If normal,
the input interface of the controller has internal fault. Please contact the manufacturer. When the
handwheel is rotating, the counter shows the received pulses, and HNDA and HNDB signals change
alternatively. If there is no counting, and HNDA and HNDB signals have no change, please check the
wire connection and whether the 5V power supply of the handwheel is normal. If the connection is
normal, but the handwheel doesn’t have 5V power supply, the internal power supply of the controller has
fault. Please contact the system manufacturer. Note: the 5V power supply is only for the handwheel.
