Startup test
Set up the communication with Master and follow
below steps.
1. Complete Parameterization of the device. Below
parameters are important to control device on PROFIBUS.
a. Parameterization Enable/Disable = 1 (Enabled)
b. Local / remote selection = 1 (Remote control)
c. Remote 1 control place = 1 (Fieldbus)
d. Remote 1 reference = 7 (Fieldbus Ref)
e. PNU927-Opern priority of param = 1
f. PNU928 Ctrl priority DOIO Data = 1
g. ProfiBus Operation Mode = 0 (ProfiDrive)
2. Select the “Standard Telegram 1” in the Configuration
step in the PLC
3. Set control word value to 0x0406 to enter ProfiDrive
State S2
4. Set control word value to 0x0407 to enter ProfiDrive
State S3
5. Set control word value to 0x047F and Set Frequency
reference t0 0x4000 to enter ProfiDrive State S4
6. Check drive is running on output frequency 100%.
7. Set control word value to 0x047E to drive stop and
ProfiDrive State S2
8. Check drive is in stop mode and output frequency 0%
Control and status words
The Control Word (PROFIBUS Parameter number (PNU) = 967)
is the principal means for controlling the drive from a
fieldbus system. It is sent by the fieldbus master station
to the drive, the adapter module acting as a gateway.
The drive switches between its states according to the
bit-coded instructions on the Control Word, and returns
status information to the master in the Status Word
(PROFIBUS Parameter number (PNO) = 968).
Control word 1 (STW1)
To improve the exchange of devices of different
manufacturers in a control application, we strongly
recommend using the device-specific bits only for the control
of manufacturer specific functions. The device-specific bits
shall not be necessary for the operation of a device in the
speed control mode and in the positioning mode (default of
the device-specific bits = 0).

Bit Value Significance Comments
0 1 ON “Switched on” condition; voltage at the power converter, i.e. the main contact is closed (if present).
0 OFF (OFF 1) Power-down (the drive returns to the “ready for switching on “condition); the drive is ramped-down
along the ramp (RFG) or along the current limit or along the voltage limit of the d.c. link; if standstill is
detected, the voltage is isolated; the main contact is opened (if present). During deceleration bit 1 of
ZSW1 is still set.
An OFF command is interruptible.
1 1 No Coast Stop (no OFF 2) All “Coast Stop (OFF2)” commands are withdrawn.
0 Coast Stop (OFF 2) Voltage is isolated.
The main contact is then opened (if present) and the drive goes into the “Switching On Inhibited”
condition; the motor coasts down to a standstill.
2 1 No Quick Stop (no OFF 3) All “Quick Stop (OFF3)” commands are withdrawn.
0 Quick Stop (OFF 3) Quick stop; if required, withdraw the operating enable, the drive is decelerated as fast as possible,
e.g., along the current limit or at the voltage limit of the d.c. link, at n / f = 0; if the rectifier pulses are
disabled, the voltage is isolated (the contact is opened) and the drive goes into the “Switching On
Inhibited” condition.
A Quick Stop command is not interruptible.
3 1 Enable Operation (Start) Enable electronics and pulses.
The drive then runs-up to the set point.
0 Disable Operation (Stop) The drive coasts down to a standstill (ramp-function generator to 0 or tracking) and goes into the
“Switched on” condition (refer to control word 1, bit 0).
