Technical features
PLD330 is a modern and available microstep stepper motor driver.
The driver has inbuilt coil short-circuit protection, back EMF effect
protection, exceeding STEP signal frequency, power unit overheating
and inbuilt automatic compensator of normal speed stepper motor
resonance.
The device works with standard control protocol STEP/DIR/ENABLE.
The module has discrete regulation of operating current of stepper
motor phases. All driver’s control inputs are optoisolated and logic
levels 2.5V, 3.3V, 5V compatible.
The driver is AUTO-SLEEP mode supplied which is turned on when
there is no STEP signal.
The device is optimal for control of bipolar and unipolar Purelogic
R&D stepper motors (PL42/PL57 series). Operation with other stepper
motors is also possible.
• New generation stepper motor driver PLD330 — 1 pcs.
• Instruction manual — 1 pcs.

Power off device before making any connections.
Do not mount the power switch after the power source (on the driver
power line).
Power switch should be installed before power supply, at ~220V side.
Do not connect the drivers in series, only ‘star’ connection is allowed.
Do not connect power supply’s «-» to ground, mass, housing, etc.
strictly observe the polarity of power supply and control signals
connections.

Fig. 4. Purelogic R&D stepper motor connection to the driver
The length of wires leading to the stepper motor from the driver must
not exceed 10 meters. Longer wires can lead to driver’s work failures.
It is strongly recommended to interlace the stepper motor wires per
phase, then put this braid to the screened metal sheath. Sheathes and
stepper motor frame must be grounded.
POWER OFF DEVICE BEFORE MAKING ANY CONNECTIONS.
Coil short-circuit protection – against wrong stepper motor coil
connection and coils linked together / ‘+’ power supply. In some cases
by interturn short-circuit of stepper motor coil, short-circuit protection
may not work because there is no exceeding of permissible alarm
current. This happens because under such coil short circuit resistance
does not equal 0 and the driver maintains the specified current.
Power surges protection is turned on if power supply is more than 35V,
for back EMF driver protection.
Protection against power section overheating – the protection turns on
when it is 170°С.
Protection against exceeding STEP signal frequency – the protection
turns on when STEP signal is given with the frequency which exceeds
the permissible for the step division range given.

Max supply voltage driver option depends on the applied stepper motor
and desired max rotation speed. Optimal supply voltage calculation
for the stepper driver is carried out according to the formula U=32*v
(stepper motor phase inductance mH), but not more than 32V.
Supply current must be chosen 50...70% from the claimed stepper
motor coil current.
Working current setting must be performed with help of dip-switches
SW3, SW4.
When there is no STEP signal more than 1 sec, the driver goes to
AUTO-SLEEP mode and reduces the coil current to the value identified
by dip-switches SW5, SW6 (the current in hold mode must be less or
equal the working current). It allows to reduce stepper motor heating
when in standstill and reduce current consumption.
Always perform all switch-overs when the driver is powered off.
For back EMF compensation we recommend to use protecting device –
dumper (module PLZ005).
PLD330 driver is optimal for bipolar and unipolar stepper motors
Purelogic R&D series PL42/PL57. Stepper motor connection to the
driver is performed as it is shown in fig. 5 (clips PH1.1[+A], PH1.2[-A]
and PH2.1[+B], PH2.2[-B]).
The driver has protection against wrong stepper motor coil connection
and coils linked together / ‘+’ power supply.
Purelogic R&D stepper motor connection to the driver is performed
according fig. 4.
Please note in case of changing phases PH1.x<>PH2.x, the motor
will start rotating in the opposite direction (inversion analogue of DIR
signal).

09. Protection functions
If you have questions please consult our technical support team.
1.2. Seller does not guarantee compatibility of the purchased product
with the one that Buyer already has or bought from third parties.
1.3. Product’s component parts and configuration can be changed by
manufacturer without notice due to the product consistent technical
improvement.
2. Conditions for warranty acceptance
2.1. The product is accepted only in the same completeness of set as it
was purchased.
3. Warranty service procedure
3.1. Warranty service is performed by testing the claimed product
defect.
3.2. If the defect is proved, warranty repair is carried out.
4. We do not assume any responsibility for glass, electric lamps,
starters and expendable materials as well as:
4.1. Damaged product caused by inappropriate transport and store
conditions, wrong connection, operation in abnormal (off-design)
mode, or in conditions which are not manufacturer-supplied (including
temperature and humidity out of limits of recommended range), having
damages due to third-party circumstances (voltage jumps, natural
disasters, etc.), also having mechanical or thermal damages.
4.2. The product with traces of foreign objects or substances impact,
including dust, liquids, insects, also objects having extraneous
inscription.
4.3. The product with traces of unauthorized tampering and (or) repair
process (traces of opening, home-made soldering, elements changing
etc).
4.4. The product with self-diagnostic function that shows improper
exploitation.
4.5. Technically complex product in respect of which assembly
and integration and start-up works were not performed by Seller
specialists or by recommended organizations, except in cases directly
regulated under goods documentation.
Max shaft rotation frequency is 30 cycles per second (under greater
rotation frequency, the torque on the step motor shaft becomes
minimal, you can reach such speed only by rotating stepper motor with
unloaded shaft under laboratory conditions, produced EMF under such
high turnover can result in failure of driver power part so for safety
reasons the driver turns off). For step division 1:1 max frequency STEP
is 6 kHz, 1:2 — 12 kHz, 1:8 — 50 kHz, 1:16 — 100 kHz. When protection
operates the driver turns off stepper motor coil, green LED goes out.
The driver restarts after OFF/ON supply voltage and error-cause
removal.
The driver allows to divide electronically physical stepper motor step -
1, 2, 8 and 16.
Thus positioning accuracy is higher. Step division mode is called
microstep division . This mode allows to reduce stepper motor
resonances at low revs but when using microstep the stated time
on stepper motor shaft is reduced. Switching of step division mode
is performed by dip-switch SW1, SW2. Step division choice must be
performed only when driver supply is OFF.
The warranty period is 12 months after purchasing and is valid only
if all operational conditions and scheduled maintenance are strictly
followed.
