1FT7 Servo Motor - High Precision & 4x Overload for Industrial
Motion The 1FT7 servo motor is a high-performance permanent magnet
synchronous motor engineered specifically for industrial motion
control applications. Leveraging premium encoder technology, it
delivers exceptional positioning accuracy and speed regulation,
paired with low torque ripple to ensure superior surface finish
quality and precise trajectory control for machine tools, packaging
lines, material handling systems and other industrial equipment.
Its standout feature lies in the 4x overload capacity under natural cooling conditions, combined with an IP67 high
protection rating and a vibration-isolated encoder, enabling stable
and durable operation even in harsh industrial environments.
Compact in design, easy to install and maintain, the 1FT7 servo
motor seamlessly integrates with SINAMICS S120 drives via the
DRIVE-CLiQ digital interface, making it a reliable, high-dynamic
and high-precision power solution for industrial automation. Product Features

Frequently Asked Questions Q1: I bought a 1FT7 motor in Europe and used it in the
high-temperature areas of Africa, but it always overheats and shuts
down. Is it a quality problem of the motor? A1: It's probably not a quality problem, but a wrong model
selection. Most standard 1FT7 models sold in Europe adopt natural
cooling, which is suitable for ambient temperatures up to 40℃.
However, the daytime temperature in many areas of Africa can soar
above 50℃, so natural cooling can't bear it. It is recommended to
replace it with a high-dynamic version with forced air cooling or
water cooling. In addition, add a sunshade to the motor to avoid
direct sunlight, and leave enough ventilation space around it. This
can alleviate the overheating problem. If the problem still exists
after replacing the model, you need to check if the load is
excessive. Long-term overloading will also cause the motor to heat
up quickly. Q2: I want to replace the old 1FT6 motor with 1FT7. Do I need to
modify the mechanical part? I'm worried it can't be installed. A2: No need to modify the mechanical part! When the 1FT7 was
designed, compatibility with 1FT6 was taken into account. The
flange size, mounting hole position and shaft diameter are exactly
the same. You can directly remove the old one and install the new
one. The key point is on the driver side: you need to change the
parameters in the SINAMICS S120 driver from 1FT6 to 1FT7.
Fortunately, the 1FT7 has an electronic nameplate that can be
automatically recognized by the driver, so modifying the parameters
is not troublesome. After installation, run a test for 30 minutes
to confirm that the motor rotation direction is correct and the
positioning is accurate, then it's okay. Q3: Using 1FT7 in North America, the voltage is 120V, and the motor
is marked 200-480V. Will it burn if connected directly? A3: Connecting directly to 120V will definitely burn the motor!
Although the 1FT7 supports a wide voltage range, the minimum is
200V. When using it in North America, you need to equip a step-up
transformer to boost 120V to more than 200V before supplying power
to the motor. In addition, don't forget to confirm the driver. It
must be a North American special model with UL/CSA certification,
otherwise it can't pass the local electrical inspection and there
will be potential safety hazards. Never modify the voltage wiring
of the motor yourself, as the warranty will be lost after
modification. Q4: Used in a food processing plant, the equipment is rinsed with
water and cleaning agents every day. Will the 1FT7 motor rust or
short-circuit? A4: The ordinary 1FT7 can't bear it. Most cleaning agents in food
processing plants are acidic or alkaline, which will corrode the
motor shell, and water flushing may seep into the interior and
cause short-circuit. You need to use a special food-grade version.
This version has an N40 protective coating, which can resist
corrosion from cleaning agents, and the protection level can reach
IP67, so it's not afraid of water flushing. In addition, when
selecting, confirm whether there is FDA certification, otherwise it
will not meet the hygiene standards of the food industry, and
problems will occur during customer inspections. Q5: The motor vibrates violently and makes abnormal noises when
running at high speed. What's the reason and how to solve it? A5: First, check two of the most common places: 1) Are the screws
of the mounting flange tightened, and tightened evenly? If the
screws are loose or not tightened evenly, the motor shaft will be
eccentric, and it will definitely vibrate and make noises when
running at high speed. Retighten the screws according to the
specified torque, and clean the debris on the flange surface. 2)
The encoder. Open the encoder cover to check if the fixing screws
are loose. A damaged encoder can also cause vibration and abnormal
noises. If the screws are okay, the encoder is probably damaged and
needs to be replaced. If both places are fine, the motor rotor may
be unbalanced, and you need to contact Siemens personnel for
dynamic balance testing. Q6: The motor broke down right after the 1-year warranty period
expired, and the maintenance cost is quite high. Is there any way
to save money? A6: Maintenance after the warranty period does require
self-payment, but you can first let the after-sales staff check the
cause of the fault clearly. Many times, it's not the core
components of the motor that are broken, but small parts such as
encoders and bearings. Replacing a small part is much cheaper than
replacing the entire motor. In addition, when you buy a motor next
time, you can purchase an extended warranty service. Generally, you
can extend the warranty period to 2-3 years with a small amount of
money. For motors used in harsh environments, buying an extended
warranty is particularly cost-effective. In addition, do a good job
in daily maintenance, clean dust regularly and check screws, which
can reduce faults and extend the service life of the motor. Q7: Used in a woodworking factory with a lot of wood chips, the
motor's encoder always breaks. How to protect it? A7: First of all, you need to replace the 1FT7 motor with IP67
protection level, which has much better dustproof effect than the
ordinary IP65. Then install a custom dust cover at the encoder end.
Note that the dust cover cannot block the motor's heat dissipation
port, otherwise it will cause the motor to overheat. Daily
maintenance is also required: blow the wood chips around the
encoder with dry compressed air after work every day, and check the
encoder wiring every month to avoid wood chips entering the
interface and causing poor contact. After such treatment, the
service life of the encoder will be significantly extended. |
