protective equipment (body protection, headgear, eye protection, hand guard).
Application as directed
•Drives are components, which are designed for installation in electrical systems or machines.
They are not to be used as domestic appliances, but only for industrial purposes according to
EN 61000−3−2.
•When drives are installed into machines, commissioning (i.e., starting of the operation as
directed) is prohibited until it is proven that the machine complies with the regulations of the
EC Directive 2006/42/EG (Machinery Directive); EN 60204 must be observed.
•Commissioning (i.e., starting of the operation as directed) is only allowed when there is
compliance with the EMC Directive (2014/30/EU).
•The technical data and supply conditions can be obtained from the nameplate and the

Installation Guide Servo Drives ENG
NTI AG / LinMot C1250-MI Page 5 / 29
Installation
•The drives must be installed and cooled according to the instructions given in the
corresponding documentation.
•The ambient air must not exceed degree of pollution 2 according to EN 61800−5−1.
•Ensure proper handling and avoid excessive mechanical stress. Do not bend any components
and do not change any insulation distances during transport or handling. Do not touch any
electronic components and contacts.
•Drives contain electrostatic sensitive devices, which can easily be damaged by inappropriate
handling. Do not damage or destroy any electrical components since this might endanger your
health!
Electrical connection
•When working on live drives, observe the applicable national regulations for the prevention of
accidents.
•The electrical installation must be carried out according to the appropriate regulations (e.g.
cable cross−sections, circuit breakers, fuses, PE connection). Additional information can be
obtained from the documentation.
•This product can cause high-frequency interferences in non-industrial environments, which
can require measures for interference suppression.
Operation
•If necessary, systems including drives must be equipped with additional monitoring and
protection devices according to the valid safety regulations (e.g. law on technical equipment,
regulations for the prevention of accidents). The drives can be adapted to your application.
Please observe the corresponding information given in the documentation.
•After the drive has been disconnected from the supply voltage, all live components and power
connections must not be touched immediately because capacitors can still be charged. Please
observe the corresponding stickers on the drive. All protection covers and doors must be shut
during operation.
Burn Hazard
The heat sink (housing) of the drive can have an operating temperature of > 80 °C: Contact with the
heat sink results in burns.
Caution - Risk of Electric Shock!
•Before servicing, disconnect supply, wait 5 minutes and measure between PWR+ and PGND to
be sure that the capacitors have discharged below 42 VDC.
•The power terminals Ph1+, Ph1-, Ph2+, Ph2- and PWR+ remain live for at least 5 minutes after
disconnecting from the power supplies.
Grounding
All metal parts that are exposed to contact during any user operation or servicing and likely to
become energized shall be reliably connected to the means for grounding.

7Power Supply and Grounding
To assure a safe and error free operation, and to avoid severe damage to system components, all
system components must be well grounded to protective earth PE. This includes both LinMot and all
other control system components on the same ground bus.
Each system component1should be tied directly to the ground bus (star pattern). Daisy chaining from
component to component is forbidden. (LinMot motors are properly grounded through their power
cables when connected to LinMot drives.)
Power supply connectors must not be connected or disconnected while DC voltage is present. Do not
disconnect system components until all LinMot drive LEDs have turned off. (Capacitors in the power
supply may not fully discharge for several minutes after input voltage has been disconnected). Failure
to observe these precautions may result in severe damage to electronic components in LinMot
motors and/or drives.
Do not switch Power Supply DC Voltage. All power supply switching, and E-Stop breaks should be
done to the AC supply voltage of the power supply. Failure to observe these precautions may result
in severe damage to the drive.
1
Inside of the C1250 drive the PWR motor GND and PWR signal GND are connected together and to the GND of the
drive housing. It is recommended that the PWR motor GND is NOT grounded at another place than inside of the drive
to reduce circular currents.

8Calibrated Measuring Amplifier (C1250-MI-XC-xS-Cxx)
The drives with the ending -Cxx are specially designed for measuring applications. They come with a factory calibration
certificate for the analog inputs on X4. The analog inputs on X4 provide a measuring error of less than 1%.
It is the user's responsibility to allow a reasonable period for recalibration. We recommend a calibration interval of 12
months.

11 Safety Wiring
The C1250 drives with the -1S option have internal safety functions:
Two Safety relays Ksr in series, which support the supply voltage for the motor drivers. There are also two feedback
contacts for each relay.
To enable the -1S drives both relays must be switched on.
Minimal wiring:
•Connect X33.8 and X33.4 to 24 VDC (from safety)
•Connect X33.7 and X33.3 to GND (from safety)
Never connect X33.8 and X33.4 to the logic supply of X4!
The overvoltage protection must be provided externally and sized according to the safety circuit of
the machine!
The drop out time of the relays is depending on the external circuitry!

DC (Diagnostic Coverage) is high (99%) assuming that the state of the feedback contacts is checked after each change of
the state of the control contacts.
The MTTFdmainly depends on the number of operations of the safety relays.
Example calculation of MTTFd:
Assuming that the safety function is requested every 20 s on a machine running 24 h per day and 7 days per week.
B10 = 10'000'000
B10d = 20'000'000 (according EN ISO 13849-1:2008 table C.1)
nop = (24 h/day * 365.25 days/year * 3600 s/h) / 20 s = 1'577'880 operations per year
MTTFd = B10d / (0.1 * nop) = 126.75 years
(This has to be limited to 100 years according to the standard for further calculations)
= high (100 years)

* The derating is depending on the situation in the cabinet. The temperature of the drive should be checked under full load (the temperature should
be stable, which may take an hour or more). This allows to verify that enough margin is there if the cabinet goes to the maximum allowable
temperature of 40° C. For example, if the drive temperature reaches 45° C and the cabinet temperature is 30° C, this would result in a drive
temperature of about 55° C at a cabinet temperature of 40° C. The warning level of the drive is configured by default to 75° C and the error level to
80° C. In this example, everything is fine. If the drive temperature is long time above the warning level, this might result in a reduced lifetime of the
drive.

13 Power Supply Requirements
13.1 Motor Power Supply
The calculation of the needed power for the Motor supply is depending on the application and the used motor.
The nominal supply voltage is 72 VDC.
The possible range is from 24 to 85 VDC.
The motor supply can rise to 95 VDC when braking. This means that everything connected to that
power supply needs a voltage rating of 100 VDC. (Additional capacitors, etc...).
Due to high braking voltage and sudden load variations of linear motor applications, only compatible
power supplies can be used (see chapter 16 Ordering Information).
13.2 Signal Power Supply
The logic supply needs a regulated power supply of a nominal voltage of 24 VDC. The voltage must be between 22 and
26 VDC.
Current to be provided from the supply:
•min. 0.5 A (no load on the outputs)
•typ. 0.7 A (all 2 outputs “on” with 100 mA load and brake with no load)
•max. 2.0 A (all 2 outputs “on” with 500 mA peak load and brake with 500 mA peak load)
Do not connect the safety relays to the 24 VDC Signal Supply!
Use a separate power supply for the safety circuit
The 24 VDC supply for the control circuit must be protected with an
external fuse (3 A slow blow)
14 Regeneration
If the power supply rises too high when breaking, connect an additional capacitor to the motor power supply.
It is recommended to use a capacitor >= 10’000 μF (install capacitor close to the drive supply!).
