Introduction
3 Introduction
3.1 System description
The "DRS11B synchronous operation card" enables a group of motors to be operated
at a synchronous angle in relation to one another or with an adjustable proportional re-
lationship (electronic gear).
The drive that specifies the position is known as the "master." This can also be an incre-
mental encoder. The drive that follows the position specification is known as the "slave".
To be able to function in this way, the master and slave motors must be equipped with
encoders. MOVIDRIVE®MDX61B with the "DRS11B synchronous operation card" op-
tion is used as the slave drive.
The "DRS11B synchronous operation card" option must be plugged into the expansion
slot and can only be operated in conjunction with the DEH11B or DER11B option.
The master and slave pulses counted are converted for the output side using parameter
P221/P222 (master and slave gear ratio factor). They are a measure for the pulses
counted per travel unit.
The system determines the difference of the distance information from master and slave
and stores this value in the form of incremental encoder signals in an internal differential
counter. Binary messages are set, e.g. "DRS SLAVE IN POS," "LAG ERROR," etc. de-
pending on the difference. The counter is evaluated differently for the various operating
modes (P223) (→section 7.3).
The controller calculates the speed correction value for the slave drive to minimize the
angle differential between the master and slave. To do so, the current angle differential
is multiplied by the parameter P220 P gain. The result is a correction value for the slave
speed.
• Master and slave run synchronously, differential value = 0 →correction value = 0
• Slave follows master, differential value > 0 →correction value > 0, slave accelerates
• Slave runs ahead of master, differential value < 0 →correction value < 0, slave de-
celerates
The value of the P gain (P220) is a significant factor for determining the movement char-
acteristics of synchronous operation control.
• If the P gain is set too high, the system tends to oscillate.
• If the P gain is set too low, the angle differential cannot be reduced in a transient state
(acceleration or deceleration).
STOP!
The slave inverter must be equipped with a braking resistor for synchronous operation
of master and slave. The master inverter may also have to be equipped with a braking
resistor for regenerative operation, depending on the application.

4.2 Project planning information
Observe the following project planning instructions:
• Do not use synchronous operation with systems that have a rigid mechanical con-
nection.
• Equip slave inverters with a braking resistor.
• They must activate an offset only if a previous angular offset has been processed.
• During project planning for a synchronous operation application, bear in mind that the
slave must be able to reduce the angle differential between itself and the master at
any time. For this reason, set the maximum speed (P302) of the slave to a value
greater than the maximum speed of the master.
If you set the maximum speed higher than the rated motor speed in the case of AC
asynchronous motors, the full motor torque is no longer available in the field weak-
ening range. This can lead to lag errors (F42) in certain master/slave combinations.
Furthermore, synchronization during the transition from free-running to synchronous
operation can be performed at maximum acceleration or using an adjustable ramp
(P24_ Synchronous operation with synchronization).
• Always activate the wire-break monitoring function with synchronous operation
(→Sec. 4.3).
• If possible, always use the same type of drives for synchronous operation.
• In the case of multiple column hoists, always use the same motors and the same
gear units (identical ratios).
• In the case of group configuration (1 master and x equal-ranked slaves), a maximum
of 5 binary inputs on the slave inverter can be connected to one binary output on the
master.
• If the master is stationary when the power supply is switched on and the power to the
slave is switched off and on again, the slave has the operating status "NO ENABLE."
• If the master is moving when the power supply is switched on and the power to the
slave is switched off, the master issues the fault "EXTERNAL TERMINAL" (F26).
When the slave is reconnected to the power supply, the slave can detect the fault
"LAG ERROR" (F42) depending on the lag error limit set (P512).
• Observe the MOVIDRIVE®MDX60B/61B operating instructions when connecting a
motor encoder to the EH11B / DER11B:X15 option.
• Note the following during operation with the option DEH11B / DER11B:
– DEH11B: The number of pulses (X14) is identical to X15 motor encoder input
– DER11B: The number of pulses is always 1024 pulses per revolution
• The following encoders can be connected at the inputs X41 and X42:
– DC 5 V TTL encoders, encoders with RS422 signal properties, sin/cos encoders
• The maximum permitted input frequency of the encoder inputs is 200 kHz
• When using synchronous encoders, the ratio of the position resolutions between the
motor encoder and synchronous encoder should lie within the range 0.1 ... 10.
• Install the encoder on the moving machine component with a positive connection
(slip-free).
• If the master is an external incremental encoder, use incremental encoders with as
high a resolution as possible. However, the maximum input frequency of 200 kHz
must not be exceeded.

Synchronous operation with wire-break monitoring of encoder connection
Project Planning
• Parameter P350 Change direction of rotation 1:
When synchronous operation control is activated, P350 must be set to NO. If the
master and slave are to operate in opposite directions, the connection sequence of
the A/A and B/B tracks at the slave input (DRS11B:X42) must be swapped over in
each pair.
• The -24 V DC connection at DRS11B:X44 is mandatory in the following cases:
– The encoder voltage supply is connected via option DRS11B
– The binary outputs (X40:9, X40:10) or DRS11B are used.
– X40:8 is used as voltage output
• Encoder monitoring at X41/X42 is only possible with TTL encoders.
4.3 Synchronous operation with wire-break monitoring of encoder connection
For fault-free synchronous operation between master and slave, wire-break monitoring
is required for the connection between master DEH11B/DER11B:X14 (incremental en-
coder simulation) and slave RS11B:X42. The following functions are available:
• "MOTOR STANDSTILL" and "DRS MAST. STOPPED"
• "/EXT. FAULT" and "/ERROR"
The only time when encoder pulses are not transferred to the slave is when the master
is at a standstill. Therefore, this status is communicated to the slave via a binary con-
nection. If the master does not report a standstill and the slave does not count any en-
coder pulses, there is either a cable break or the master encoder is defect. As a result,
the slave switches off and communicates its status to the master via an additional con-
nection.
Required
connections
• Program one binary output of the master to the function "MOTOR STANDSTILL".
Connect this output to a binary input on the slave, that is programmed to the function
"DRS MAST. STOPPED.".
• Program one binary input of the master to the function "/EXT. FAULT". Connect this
input to a binary output on the slave, that is programmed to the function "/ERROR."
NOTE
Additional encoder monitoring can be activated with P516 or P519 (→Sec. 6).

4Synchronous start/stop
Project Planning
4.4 Synchronous start/stop
For MOVIDRIVE®synchronous operation, the following mixed mode is possible:
• Master is less dynamic or as dynamic as the slave
• Master is an incremental encoder
• Brake function OFF:
No controller inhibit (DI00 "/CONTROLLER INHIBIT" = "1") and no ENABLE
(DI03 = "0") →slave is at a standstill at speed 0 subject to speed control
No controller inhibit (DI00 "/CONTROLLER INHIBIT" = "1") and ENABLE (DI03 = "1")
→slave synchronizes itself with the master position.
• Brake function ON:
When both master and slave are at a standstill at speed 0, the slave brake is applied.
The following table lists the settings or cable connections for the above master/slave
combinations with regard to synchronous starting/stopping and activated wire-break
monitoring.
NOTE
The master and slave(s) must be able to start / stop synchronously in both options.
This is the prerequisite for correct operation. As a result, combinations in which the
master is more dynamic than the slave are not permitted.
Master parameters Slave parameters Comment
Wire-break monitoring:
DO01 = "MOTOR STANDSTILL"
Synchronous start/stop:
DO02 = "OUTPUT STAGE ON"
Wire-break monitoring:
DI terminal = "DRS MAST. STOPPED"
Synchronous start/stop:
DI terminal = "DRS SLAVE START"
Enable slave permanently.
Binary outputs DO01 and
DO02 are no longer available
on the master.
STOP!
When the brake function is activated, the slave terminal "DRS SLAVE START" must
always be programmed and wired up. This also applies when the master is only an
incremental encoder; in this case, an external controller must give the signal DRS
"SLAVE START".
When the brake function is deactivated, the position is held subject to position control
when the signal "DRS SLAVE START" is revoked or if the drive reaches the stop area
(P510).

Synchronous operation with synchronous encoder
Project Planning
4.5 Synchronous operation with synchronous encoder
Position measurement has to be carried out via an extra incremental encoder in all ap-
plications in which power transmission between the motor shaft and the machine is non-
positive and thus slip is to be expected. This incremental encoder must be installed on
the moving machine component with a positive connection. In the following section, this
encoder is referred to as a synchronous encoder. The synchronous encoder is needed
to record the current position of the slave (G2). The encoder installed on the motor shaft
is still used to record the current speed (G1) of the drive.
The higher the resolution of the encoder (number of pulses counter per travel unit), the:
• more accurately the slave can follow the master
• more rigidly the synchronous operation control can be set (large P factor)
• smaller the angle error will be during acceleration and deceleration
However, due to the calculation accuracy of the synchronous operation controller, the
ratio of the position resolutions (incr./mm) between the motor encoder and synchronous
encoder should lie in the range 0.1 ... 10 . If the ratio is outside of this range, in many
cases a different synchronous encoder additional gear can be used for a more favorable
ratio.
• Setting the master / slave gear ratio factor →Sec. 6.3
• Setting the slave encoder / slave synchronous encoder factor
A mechanical gear ratio can be set between the incremental encoder to record the
motor speed (G1) and between the incremental encoder for position measurement
(G2). This gear ratio is set with parameter P231 (factor slave encoder) / P232 (Factor
slave sync. encoder).
– Equal-ranked:
The signal of the master encoder at X42 is passed to the next slave via X43. In
this way, all slaves receive identical master encoder signals.
–Chain:
The signal of the synchronous encoder at X41 is passed to the following slaves
via X43. In this way, the synchronous encoder signal becomes the master encod-
er signal of the following slave.

X10:10 DGND on the MOVIDRIVE®basic unit.
• Enable command on slave inverter for synchronous operation (with standard default
assignment of DI01, DI02 and DI03):
– DI00 (X13:1)= "1" (/Controller inhibit), DI03 (X13:4) = "1" (Enable) and
– DI01 (X13:2) = "1" (CW) or DI02 (X13:3) = "1" (CCW)
Important: During synchronous operation, the direction of rotation of the slave is de-
termined by the direction of rotation data of the setpoint pulses passing from the mas-
ter to the slave.
• If the master and slave drives turn in the same direction (CW direction for master
= CW direction for slave), the tracks are wired 1:1 (→following figure).

• If the master and slave drives turn in the opposite direction (e.g. output shafts of
gearmotors with same number of gear ratio steps are opposite each other):
– Swap the connection sequence of tracks A/A and B/B in pairs between the master
output "incremental encoder simulation" and slave input "Master encoder" (→fol-
lowing figure).

• If two slave drives turn in the same direction (CW direction for slave n = CW di-
rection for n+1), the tracks are wired 1:1 (→following figure).
