for switching on again (acknowledgement) after a fault shut-off (fault status
at digital output "D"). Switch-on/acknowledgement takes place with a change
of the signal level from 0 to 1.

Digital output signals "E" (Channel A, red) and "IST" (Channel B, grey)
for information about speed and direction of rotation
Each of the two open collector outputs can be read out separately as actual
speed value information. A rectangular signal is present at both outputs, and
can be evaluated either as a frequency or as a number of pulses (e.g.
number of rising edges per revolution). By default, the frequency is defined
such that 6 pulses (signal periods) per revolution are output.
This results in the following relationship:
Signal frequency * 10 = speed in rpm.
For design variants that deviate from this, the information in the product
specification must be taken into account.
When evaluating both outputs, a 2-channel encoder replacement signal is
obtained; as a result, both the double speed information and the direction of
rotation can be identified via the assignment of the leading channel.
NOTE
Outputs E and IST are not short-circuit proof and have no
reverse polarity protection.
If the output is overloaded or incorrectly poled, this will damage
the output wiring.

5 FUNCTIONAL DESCRIPTION
The VDC-3-49.15 drive system is an electronically commutated external
rotor motor with integrated operating and control electronics. Commutation
takes place in sinus commutation based on a field-oriented control (FOC).
The drive system works as a speed controller with speed limiter and ramp
function as well as with a current controller (torque controller) with torque
limitation.
5.1 Speed set value input function
Note: Specify the speed set value to operate the motor.
According to the illustration in Chapter 4.2 (analogue set value input "S1"),
this input can be used to specify a set value that corresponds to a speed in
the range from 0 rpm to n
listed in the specification and the listed control accuracy, the drive attempts
to adjust the speed to the specified set value, even when there are load
fluctuations. The same function is also available for the drives in the version
with set value input as a frequency signal. Here, a defined frequency signal
corresponding to the product specification must be applied at input "F+".
5.2 Torque set value input function
Note: Specify the torque set value to operate the motor.
According to the illustration in Chapter 4.2 (analogue set value input "S2"),
this input can be used to specify a set value via this input that corresponds to
a torque in the range from 0 to 100 % (peak torque, see "I
limitation"). Within the specified tolerance range, the maximum attainable
torque of the drive can be configured. In this way, movement operations can
be limited to a maximum permitted torque if necessary.
In conjunction with a corresponding speed set value, this function enables
torque-controlled winding or coil processes to be implemented, for example.
5.3 Actual value output/encoder signal function
For external monitoring of the actual speed of the drive, the two outputs "E"
and "IST" are available. Each of the two outputs, which are switched as open
collector, deliver a frequency signal with 6 pulses per revolution, for which
the following relationship applies:
Signal frequency * 10 = speed in rpm.
Via the electrical phase offset of 90° of both signals to each other, when
evaluating both channels, an encoder replacement signal with rotation
direction information and 12 pulses per revolution are obtained. For special
designs, a higher number of pulses can also be implemented with a limited
speed range and limited maximum speed. For detailed information in this
regard, refer to the respective product specification.
The protection function takes effect at the limit values listed in the
specification (relative to the terminal voltage U
If one of the switching thresholds is reached, the output stage is switched off
to protect the system and the drive starts freewheeling.
If the drive exceeds the limits for short periods (< 250 ms, occurrence of any
fault peaks in the power supply), it resumes running if the voltage range
returns to a permitted level within this time.
If the limits are exceeded for a longer period (>= 250 ms - interpreted as a
fault in the system), the output stage is shut off and an fault-signal is output
at status output "D".
By acknowledging the enable input "C" (change of signal level 0 to 1), status
output "D" is reset and the drive is again ready for operation.
5.5 Overtemperature protection function
An NTC on the printed circuit board (close to the power stage) protects the
drive from gradual overheating.
If the NTC reaches a temperature of approx. 110 °C, the output stage is shut
off. The status output "D" outputs an fault-signal that remains pending until it
is acknowledged successfully.
After enable input "C" is "acknowledged" with a rising switching edge, the
drive can be switched back on.
If the motor switches off due to overtemperature, for thermal protection of the
drive, successful acknowledgement is not possible until the NTC
temperature falls back below 100 °C.
5.6 I2t peak current limitation function
The I2t peak current limitation function enables an increase of the torque to
the respective specified peak torque. A so called threshold current is used to
determine the amplitude at which the squaring of the portions of the current
that lie above the threshold value begins.
In the initial state, the threshold current is close to the maximum permitted
winding current, so that depending on the environmental and operating
conditions, it is well possible for the motor to be operated at peak torque for
a number of minutes. If the internal temperature threshold value is reached,
the threshold value of the current is lowered and squaring of the portions of
the current in excess of the threshold value begins. With loading of the I
memory, the available winding current is then lowered successively; as a
result, the drive is increasingly limited in order to prevent an overload.
5.7 Acceleration and braking ramp function
The maximum possible dynamic behaviour of the drive is defined via an
internally defined parameter value that affects acceleration and braking in
inal installation
the same way. The slope of the ramp, specified as a max. possible change
of speed per unit of time, is thus limited to the following values:
Ori
24 V drive version: max. 16 rpm/ms
48 V drive version: max. 25 rpm/ms
Ex. for the 24 V drive version:
For an external set value jump from 0 to 1600 rpm, the internal set speed of
the motor increases from 0 to 1600 rpm via a corresponding ramp function
within 100 ms.
Usually, this limitation is noticeable only when the motor without load. In this
case, it serves to optimise the control and transient response to the target
speed.
).
ZK
5.8 Safe braking operation
Activating the braking function via control inputs "A/B" or via a negative set
value jump activates a controlled braking operation.
The energy released during braking is fed back and the intermediate circuit
voltage increases. To protect the drive, when the max. reverse voltage is
reached, the braking operation is interrupted and the power stage is disabled
for a short period (freewheeling).
As soon as the voltage falls back below a threshold value defined by a
hysteresis, the braking function is automatically re-enabled, braking energy
is fed back and the intermediate circuit voltage increases again.
This process repeats itself at short intervals until the motor has reached the
new set value speed or has come to a standstill.
5.9 "Zero speed" function
The "Hold zero speed" function can be activated either by specifying a
corresponding speed set value or corresponding signal on the two digital
inputs "A / B".
If an attempt is made to move the motor shaft in this state, the deviation from
the control-set-value is recognized and integrated over the time. The drive
responds with a counterholding torque which increases to the peak torque
depending on the displacement.
NOTE
The "Zero speed" function does not guarantee that a set
position will be maintained exactly.
Æ Ensure that any slight movement does not have any
harmful consequences.
NOTE
s a result of disturbances, even when the motor is
without load, the rotor can turn a few degrees out of the
original position over time in "Zero speed" operating state
Exactly maintaining a set position can not be guaranteed.
Æ Ensure that any slight movement does not have any
harmful consequences.

VDC for max. possible torque).
⇒ Switch on the high level at the enable input "C" to make the drive ready
for operation.
⇒ Switch on/adjust the analogue set value for the speed (motor starts)
until the desired operating point is reached.
NOTE
If the drive is plugged in or unplugged with the voltage
turned on, high voltage peaks can occur.
The integrated electronics can be damaged (drive is not "hotplug compatible").
Æ Only plug in/unplug the drive system when the supply
voltage is switched on/off.
6.4 Integrated protective functions
The integrated protective functions ensure that the drive shuts off
automatically under certain operating conditions or in case of certain faults.
For a more detailed description, refer to Chapter 5.
7 MAINTENANCE, MALFUNCTIONS, POSSIBLE CAUSES AND REMEDIES
⇒ Do not perform any repairs on your drive system.
⇒ Return the drive system to ebm-papst for repair or exchange.
7.1 Troubleshooting
When switching on
Malfunction / error Possible cause Possible remedy
Missing set value signals at inputs S1 and S2Specify desired set value
Motor does not start, the power
supply is switched on and within the
specified range
The motor does not turn, the power
supply and control signals are
connected.
Motor accelerates briefly, then
switches off and runs down, fault
signal "D" is set.
In operation
Malfunction / error Possible cause Possible remedy
Motor makes "clacking noises" when
braking function is activated or there
is a negative set value jump
When operated for longer periods,
inal installation
the motor torque output declines
Ori
When operated for longer periods,
the motor stops turning
Missing digital signal at one of the inputs
(A / B)
Missing signal level change (change from
0 to 1) at input "C" to set the motor to ready
state.
Load/required start-up torque are too high.Reduce load or check motor dimensioning.
Mechanical blockage Switch off drive, remove mechanical blockage in the powertrain and
Faulty connection Check that pin configuration and control signals are correct, see
Drive defective Replace drive
High load or high acceleration with power
supply that is not designed to bear this.
Power supply reaches performance limit,
voltage drops sharply and drive detects
undervoltage.
Braking function:
Motor goes into brake operation, the fedback energy causes a voltage increase in the
intermediate circuit; when the max. reverse
voltage is reached, controlled brake
operation begins in order to protect the
system (refer to Chapter 5.8).
Thermal overload: Motor is operated too long
at high load/at elevated ambient
temperature. Motor heating causes lowering
of the winding current by the I
limitation
Thermal overload: Motor is operated too long
at high load/at elevated ambient
temperature. Motor heating finally causes a
shutoff via the integrated temperature
monitoring.
2
t peak current
Connect at least one of the two inputs for the desired operating
mode/direction of rotation
Switch on signal level at Input C again (change from 0 to 1)
attempt to restart
Chapter 4 and Chapter 6
If possible, reduce load or acceleration.
In the other case, check the dimensioning of the power supply and
use a more powerful power supply.
Use set value ramps instead of set value
reaction is needed, the fed-back energy can be removed more
quickly via an additional brake chopper in the intermediate circuit.
Check load point, ambient conditions and possibilities for heat
dissipation.
Reduce load, lower ambient temperature or provide better heat
dissipation.
Check load point, ambient conditions and possibilities for heat
dissipation.
Reduce load, lower ambient temperature or provide better heat
dissipation.
The drive cannot be switched on again until the NTC temperature
falls back to <100 °C.
After a fault or safety shut-off occurs, an fault-signal is transmitted at output
"D" and the power stage is switched off. The drive cannot be switched on
again until the enable input "C" (switching with a rising switching edge) is
acknowledged.
NOTE
If a fault remains even after you carry out the remedies
described here, please contact ebm-papst.
7.3 Cleaning
NOTE
Possible damage of the drive system during cleaning
Danger of malfunctions.
Æ Do not clean the drive system using a water jet or high-
pressure washer.
