Introduction
PES-2405
PES-2405, stepper motor controller Ⅱ, is a smart expansion board for PHPoC boards. With this
board, you can accurately control various stepper motors.
Highlights of PES-2405
bi-polar stepper motor controller
driving modes: micro step(maximum division rate: 1/32)
motor voltage: DC 4 ~ 18[V]
maximum current on each coil: 1[A]
current comsumption: approximately 30[mA]
※ Caution: PES-2405 requires a PHPoC board which has a firmware 1.3.0 or higher version.
What is the Smart Expansion Board?
A smart expansion board has own devices and firmware unlike the other
expansion boards. This board communicate in a master-slave protocol through
the designated port. Two or more smart expansion boards can be connected to
one PHPoC board and each of them required to be setting a slave id.

Connecting to a unipolar stepper motor
If you want to connect a unipolar stepper motor to PES-2405 refer to two examples below.
Supplying power
GND and VM are input port of supplying power(DC 4 ~ 18V) to run motors. Supplying power
through this port is positively necessary. Check the DC polarity when you input the power.

2. Digital input port
This port is used to connect limit switches and cannot be used for other purposes.
An example of connection with limit switches is as follows:
G means ground and all ground pins are connected each other
0, 1, 2 and 3 are the index number of input ports and all of them are pulled up
3. SLAVE ID Switch
A slave ID is used when PHPoC board identifies each smart expansion board. So, each smart
expansion board, which is connected to a PHPoC board, should have a unique slave ID. The slave ID
can be set one of the numbers from 1 to 14 by 4 DIP switches as follows:

4. LED
PES-2405 has 2 status LEDs. The one, on the top of the board, is connected to 3.3V and the other
one, on the bottom of the board is connected to 5V. The operations of both LEDs are the same and
they are as follows:
about ID setting
state operation
normal repeat On/Off in every second
abnormal blinks very quickly
about running motor
state operation
ready repeat On/Off in every second
running shortly turned on 4 times in every second
locked shortly turned off 4 times in every second

How to Use
The steps for using PES-2405 are as follows.
1. Connect to a PHPoC board
PES-2405 cannot be used alone. Be sure to connect to PHPoC board.
2. Install Software (IDE)
PHPoC Debugger is a software which is used for configuring PHPoC products and developing
PHPoC script. It is required to install this software on your PC because PES-2405 must be controlled
by PHPoC.

3. Use SPC Library and Sample Codes
The SPC library is for smart expansion boards such as PES-2405. This library makes it easy for you to
use smart expansion boards. Refer to the manual page of SPC library for more information.

Current limiting
A command vref is for current limiting. This is necessary to control motors.
"set vref (state) (value)"
The argument state means one of three states which requires to set limiting current.
state description
stop the limiting current to keep the stop state
drive the limiting current to run motors
lock the limiting current to keep the lock state
The argument value means the amount of current and there are 16 levels from 0 to 15. If you set
this value to 5, PES-2405 limits the current of the specific state to 5 of 15.
examples of setting limiting current
spc_request_dev($sid, "set vref stop 2");
spc_request_dev($sid, "set vref drive 8");
spc_request_dev($sid, "set vref lock 0");
Setting a resonance range
A command rsnc is for setting a resonance range.
"set rsnc (low_pps) (high_pps)"
The argument low_pps and high_pps mean the minimum and maximum values of the resonance
range, respectively. When the resonance range is set, PES-2405 controls at the speed set in high_pps
when the rotation speed falls within the resonance range.
an example of setting a resonance range
spc_request_dev($sid, "set rsnc 120 250");

Setting a speed
A command speed is for setting a speed. This command is available when you want to set a speed
in advance of controlling your motor.
"set speed (pps)"
The argument pps means a speed. The unit of this value is pps(pulse per second) and PES-2405
provides 240,000[pps] as its maximum speed. However, the actual maximum speed depends on the
type, voltage and loads of the stepper motor.
When you set the speed, if you put k after setting value, it is possible to perform scaling up to 1000
times. For example, 1000 and 1k mean the same value.
an example of setting a speed
spc_request_dev($sid, "set speed 400");
spc_request_dev($sid, "set speed 4k"); // the same result with "set speed 4000"
Setting acceleration and deceleration
A command accel is for setting acceleration and deceleration. This command is available when you
want to set acceleration and deceleration in advance of controlling your motor.
"set accel (accel) [decel]"
The argument accel and decel mean the acceleration and deceleration respectively. The acceleration
is a mandatory but the deceleration is an optional. If the deceleration is omitted, it is automatically
set to the same value of the acceleration. The unit of both is pps/s(pps per second) and PES-2405
provides 2,400,000[pps/s] as its maximum value.
When you set these values, if you put k after setting values, it is possible to perform scaling up to
1000 times. For example, 1000 and 1k mean the same value.
examples of setting acceleration and deceleration
spc_request_dev($sid, "set accel 1000"); // the same result with "set accel 1000 1000"
spc_request_dev($sid, "set accel 1000 0");
spc_request_dev($sid, "set accel 0 1k"); // the same result with "set accel 0 1000"
spc_request_dev($sid, "set accel 1k 2k");

Setting a counter position
A command pos is for setting a counter position. This command is valid only when controlling
stepper motor with goto and is not reflected when controlling with move.
"set pos (pos)"
The argument pos means a counter position. This value is a signed 32-bit integer and can have a
value between -1000000000(1 billion) and [phone].
When you set the counter position, if you put k after setting value, it is possible to perform scaling
up to 1000 times. For example, 1000 and 1k mean the same value.
an example of setting a counter position
spc_request_dev($sid, "set pos 400");
spc_request_dev($sid, "set pos 80k"); // the same result with "set pos 80000"

PES-2405 User Manual > How to use > Controlling by goto
2019-03-04 Sollae Systems page 20 of 28
Controlling by goto
A command goto is for controlling a stepper motor based on the initial position, not the current
position of the motor.
This method can be used even when the motor is running.
"goto [sign](pos) [speed] [accel] [decel]"
※ Caution: there is no space between [sign] and (pos)
Descriptions of the arguments are as follows:
argument description mandatory/optional
sign direction, "+"(forward) or "-"(reverse) optional(default: "+")
pos target counter position mandatory
speed speed(unit: pps) optional
accel acceleration(unit: pps/s) optional
decel deceleration(unit: pps/s) optional
The argument pos is based on the initial position, not the current position of the counter.
If the decel(deceleration) is omitted, it is automatically set to the same value of the acceleration.
an example of using goto
<?php
include_once "/lib/sd_spc.php";
spc_reset();
spc_sync_baud(115200);
$sid = 1;
spc_request_dev($sid, "set mode 4");
spc_request_dev($sid, "set vref stop 2");
spc_request_dev($sid, "set vref drive 8");
spc_request_dev($sid, "set rsnc 120 250");
spc_request_dev($sid, "set pos -400");
spc_request_dev($sid, "goto +400 200 0");
sleep(1);
spc_request_dev($sid, "goto -400 200 0");
sleep(1);
spc_request_dev($sid, "goto +400 200 0");
while((int)spc_request_dev($sid, "get state"))
usleep(1);
?>
※ This command can be used even when stepper motor is in operation. Therefore, if a new goto
command is executed while the motor is running, it is executed immediately.
