1.2.1 AS-Interface
Overview
The AS-Interface (actuator sensor interface, AS-i) is an open international standard for
fieldbus communication between distributed actuators and sensors at the lowest control
level.
AS-i complies with the IEC 61158 / EN 50295 standards and was specifically designed for
connecting binary sensors and actuators that comply with these standards. AS-i makes it
possible to replace point-to-point cabling of the sensors and actuators by a bus line.

Functions
3.3 Basic functions / parameters
3.3 Basic functions / parameters
Definition
Basic parameters are "central" parameters required by a range of device functions.
3.3.1 Rated operating current
Here, you can enter the rated operating current that the branch (switchgear and motor) can
carry without interruption. This is usually the rated motor current. The setting range depends
on the output class of the M200D motor starter (0.15 ... 2 A or 1.5 ... 12 A).
NOTICE
The rated operating current is one of the key parameters.
The rated operating current must always be set if motor protection is to be ensured via the
electronic overload relay.
The overload relay can be deactivated.
In this case, motor protection must be ensured by means of a thermistor in the motor.
Notes
● On the motor starter, the default rated operating current is set to the minimum value.
● The rated operating current for the M200D AS-i Basic motor starter is set by means of the
rotary coding switch. For more information, see Parameterization via local setting
(Page 72).
3.3.2 Protection against voltage failure
If the supply voltage fails, the last overload message "Overload" is retained.

Functions

3.4 Fieldbus interface
Response to CPU / master STOP
If the fieldbus interface is interrupted, all control signals are set to 0.
Group diagnosis
Reference
Note
This is only relevant in "automatic" mode.
The controller is informed of whether or not a group fault message is present in the device
when "I/O fault bits" on the SAP status tab (S1 = 1) is set. The AS-i master enters the S1
value in the list of I/O faults (LPF) that have been signaled. The controller can read this list
via the "GET_LPF" command and then query a specific diagnostic value from the slave (see
Diagnostics via parameter channel (parameter echo) (Page 84)).
also
The motor st
arter issues a fault message if a fault is present. In this case, the SF LED lights
up red.
For more information, refer to the documentation for your AS-i master.

3.5 Motor control
3.5 Motor control
3.5.1 Control function: reversing starter
Description
This control function allows the motor starter to control the direction in which motors rotate.
An internal logic prevents both directions of rotation from being activated simultaneously.
The delayed switchover from one direction of rotation to another is implemented by means of
the lock-out time, which is permanently set to 150 ms.
This function only applies to reversing starters.
3.5.2 Brake output
Description
A motor-mounted mechanical disk or spring-loaded brake is used to brake the motor. The
brake is controlled via the brake output.

3.5 Motor control
Brake output
Externally-supplied motor brakes are usually powered via a jumper on the motor terminal
board.
Since switching the motor and brake simultaneously can increase wear and tear to the
brake, all M200D motor starters can be fitted with an optional electronic brake controller.
Depending on the order variant, the following externally-supplied brake coils can be
controlled:
● 400 V AC / 230 V
(The brake rectifier must be installed in the motor. The rectifier input is controlled via the
motor starter).
● 180 V DC
(A rectifier is not required for the brake in the motor because the motor starter provides
the 180 V DC. In this way, brake coils for 180 V DC can be switched directly).
The brake voltage is fed to the motor together with the motor infeed via a joint cable (e.g.
2
6 x 1.5 mm
). For more information about connecting the brake output, see section Brake
output (Page 60).
Brake release delay at startup
A fixed ON-delay time of 40 ms is set for the M200D AS-i Basic motor starter to prevent wear
and tear to the brake (e.g. the motor output is activated 40 ms after the brake output).
In reversing mode, the release delay does not begin until the lock-out time has expired.

3.6.1 Thermal motor model
Description
The approximate temperature of the motor is calculated using the measured motor currents
and device parameters "Rated operating current" and "Tripping class". This indicates
whether the motor is overloaded or functioning in the normal operating range.
Motor protection shutdown response
You use this device parameter to specify how the motor starter is to respond in an overload
situation:
● Shutdown without restart (AUTO RESET = off)
Following an overload situation, the shutdown command cannot be reset until the motor
model has fallen below the reset threshold and after a reset command has been issued
(trip reset).
● Shutdown with restart (AUTO RESET = on)
WARNING
Motor restarts automatically if AUTO RESET is on.
Can Cause Death, Serious Injury, or Property Damage
The motor starter restarts automatically after the recovery time if a start command is
present (autoreset). (autoreset).
Make sure that you take appropriate measures to exclude the risk of hazardous conditions.

Trip class
The trip class (CLASS) specifies the maximum time within which a protective device must
trip from a cold state at 7.2 x the setting current (motor protection to IEC 60947). The M200D
AS-i Basic trip class is set permanently to CLASS 10 and can be deactivated.
If the setting is changed to CLASS OFF, the "thermal motor model" function is deactivated
along with the accompanying messages. With the M200D AS-i Basic, the thermal motor
model is deactivated by means of the rotary coding switch for setting the operating current
(CLASS OFF position).

Deactivation rule
To ensure motor protection, the motor cannot be switched on when the temperature sensor
is deactivated and, at the same time, CLASS OFF is set. This is indicated on the M200D ASi Basic with either an alarm (if an ON command is not present) or a fault (if an ON command
is present).
Recovery time
The recovery time is the time defined for cooling after which the system can be reset
following an overload trip. The recovery time for the M200D AS-i Basic is set permanently to
90 s.
Trip reset signals present during the recovery time have no effect.
Voltage losses occurring before this time expires can prolong the recovery time.

Prewarning limit for motor heating
The motor starter also assumes a prewarning role, that is, it issues a warning if the motor
temperature limit is exceeded. The prewarning limit for the M200D AS-i Basic is 90 % of the
motor heating value. The motor is shut down at 100 %.
The alarm can be read via Diagnostics via parameter channel (pa

3.6.2 Temperature sensor
Description
Temperature sensors are used to directly monitor the motor winding temperature. This
indicates whether the motor is overloaded or functioning normally. If temperature sensors
are installed in the motor stator winding (order option for the motor), the M200D motor starter
can use these to monitor the motor.
Shutdown without restart

• Shutdown without restart
• Shutdown with restart
• CLASS 10
• CLASS OFF
M200D motor starters can evaluate one temperature sensor circuit.
Temperature sensor
You can activate or deactivate this parameter depending on whether or not a temperature
sensor is installed in the motor. The setting is made by means of the DIP switch on the
device.
Two types of temperature sensor are supported:
● Thermoclick.
This is a switch that opens at a certain winding temperature.
● PTC type A.
This is a PTC thermistor with a characteristic to IEC 60947-8.
When the PTC type A temperature sensor is active, temperature sensor monitoring is also
activated (see below).

Motor protection shutdown response
You can use this parameter to determine how the motor starter is to respond to a
temperature sensor or thermal motor model overload:
● Shutdown without restart (AUTO RESET = off)
● Shutdown with restart (AUTO RESET = on)
WARNING
Motor restarts automatically if AUTO RESET is on.
Can Cause Death, Serious Injury, or Property Damage
The motor starter restarts automatically after the recovery time if a start command is
present (autoreset). (autoreset).
Make sure that you take appropriate measures to exclude the risk of hazardous conditions.
Temperature sensor monitoring
Temperature sensor monitoring is activated when a PTC type A temperature sensor is
parameterized.
This device parameter monitors the temperature sensor cable for interruptions (wire
breakage) and short-circuits. The motor is shut down if either of these scenarios occurs.
Settings
The possible settings for the M200D AS-i Basic motor starter can be found in section
Parameterization via local setting (Page 72).

3.7.1 Current limit values
Description
The motor current and current limit values can be used to determine different system
statuses:
System status Current value Protection by
Motor blocked Very high current flowing Blocking protection
Motor runs at no load (e.g.
because system is damaged)
Response to residual current detection
Residual current detection responds when the motor current in all three phases falls below
18.75 % of the set rated operating current. In this case, the motor starter shuts down the
motor.
Very low current flowing
(< 18.75 % of Ie)
Residual current detection
Residual current detection is deactivated by setting the rotary coding switch to
"CLASS OFF".
Note
When the motor is switched on, residual current detection is suppressed for around 1
second.
Blocking current monitoring
The blocking current specifies how much current is consumed by the motor (at rated voltage)
when the axis blocked.
The blocking current monitoring function detects when a motor axis is blocked mechanically.
The block causes the motor to consume more power. The "blocking current" is a defined
monitoring threshold for the motor current consumption.
It is monitored as follows:
When the motor starts, the tripping limit for the blocking current is set permanently to 800 %
of the rated operating current for a period of 10 s. During operation, the "blocking current"
tripping limit is set permanently to 400 % of the rated operating current.
If the blocking current is exceeded, the motor starter detects blocking. Blocking time
monitoring is activated as of the point at which the blocking current is exceeded. If the
blocking current flows for longer than the blocking time, the motor starter automatically
generates a shutdown command.

Blocking time
Note
If the blocking time expires and the system is still blocked, the motor starter is shut down.
The blocking time is the time a block can be present before the motor shuts down. If the
blocking time expires and the system is still blocked, the motor starter is shut down. The
blocking time in the M200D AS-i Basic is set permanently to 1 s.
