6 - PVD 3622_GB_TM_January 2014.Docx
1.2.2. General Safety Rules
Generality
DANGER: The installation, commission and operation must be performed by
qualified personnel, in conjunction with this documentation.
The qualified personnel must know the safety (C18510 authorization,
standard VDE 0105 or IEC 0364) and local regulations.
They must be authorized to install, commission and operate in accordance
with established practices and standards.
Electrical hazard
Servo drives may contain non-insulated live AC or DC components. Respect
the drives commissioning manual. Users are advised to guard against
access to live parts before installing the equipment.
Some parts of the motor or installation elements can be subjected to
dangerous voltages, when the motor is driven by the inverter , when the
motor rotor is manually rotated, when the motor is driven by its load, when
the motor is at standstill or stopped.
For measurements use only a meter to IEC 61010 (CAT III or higher).
Always begin using the highest range. CAT I and CAT II meters must not be
used on this product.
Allow at least 5 minutes for the drive's capacitors to discharge to safe
voltage levels (<50V). Use the specified meter capable of measuring up to
1000V dc & ac rms to confirm that less than 50V is present between all
power terminals and between power terminals and earth.
Check the drive recommendations.
The motor must be permanently connected to an appropriate safety earth.
To prevent any accidental contact with live components, it is necessary to
check that cables are not damaged, stripped or not in contact with a rotating
part of the machine. The work place must be clean, dry.
General recommendations :
- Check the wiring circuit
- Lock the electrical cabinets
- Use standardized equipment
Mechanical hazard
Servomotors can accelerate in milliseconds. Running the motor can lead to
other sections of the machine moving dangerously. Moving parts must be
screened off to prevent operators coming into contact with them. The
working procedure must allow the operator to keep well clear of the danger
area.
Burning Hazard
Always bear in mind that some parts of the surface of the motor can reach
temperatures exceeding 100°C.

3.1. Motor selection
3.1.1. Altitude derating
From 0 to 1000 m : no derating
From 1000 to 4000 m : torque derating of 5% for each step of 1000 m for TMW
From 1000 to 4000 m : torque derating of 10% for each step of 1000 m for TMA
3.1.2. Temperature derating
3.1.2.1. Natural cooled motor
The maximal temperature for natural cooling is 40°C. But, it is possible to increase a
little bit the ambient temperature above 40°C, with a torque reduction. The following
formula gives an indicative about the torque derating at low speed. But in any case
refer to PARKER technical department to know the exact values
At low speed the torque derating is given by the following formula for an ambient
temperature > 40°C.

3.1.3. Thermal equivalent torque (rms torque)
The selection of the right motor can be made through the calculation of the rms
torque Mrms (i.e. root mean squared torque) (sometimes called equivalent torque).
This calculation does not take into account the thermal time constant. It can be used
only if the overload time is much shorter than the copper thermal time constant.
The rms torque Mrms reflects the heating of the motor during its duty cycle.
Let us consider:
- the period of the cycle T [s],
- the successively samples of movements icharacterized each ones by the maximal
torque Mi[Nm] reached during the duration  ti[s].
So, the rms torque Mrms can be calculated through the following basic formula:
Example:
For a cycle of 2s at 0 Nm and 2s at 100Nm, the rms torque is
Illustration :
The maximal torque Midelivered by the motor at each segment iof movement is
obtained by the algebric sum of the acceleration-deceleration torque and the
resistant torque.
Therefore, Mmax corresponds to the maximal value of Mi.

15 - PVD 3622_GB_TM_January 2014.Docx
Selection of the motor :
The motor adapted to the duty cycle has to provide the rms torque Mrms at the rms
speed(*) without extra heating. This means that the permanent torque Mnavailable at
the average speed presents a sufficient margin regarding the rms torque Mrms.
(*) rms speed is calculated thanks to the same formula as that used for the rms
torque. The mean speed cannot be used (in general mean speed is equal to zero).
Only use the rms speed.
Furthermore, each Mi and speed associated Ωi of the duty cycle has to be located in
the operational area of the torque vs speed curve.

3.1.4. Drive selection
Drive selection depends on its rated power and its mode selection which leads to the
maximal current duration.
Please refer to the drive technical documentation for any further
information and to select the best motor and drive association.
AC890 PARKER Parker drive example:
The rated current provided by the AC890 Parker drive depends on its rated power
and its mode selection. Vectorial mode or Servo mode for a power < 37 kW,
Constant torque or Quadratic torque for a power > 37 kW.
Once the mode selection set, the rated current corresponds to 100%.
(The rated current with the Quadratic mode selection is greater than with the
Constant torque mode selection.)

Example n°1 :
The application needs:
- A rms torque of 4000 Nm at the rms speed of 100 rpm,
- An acceleration torque of 7000 Nm,
- A maximal speed of 140 rpm.
Selection of the motor:
The selected motor is the type TMW306LR.
The nominal speed is equal to 125 rpm.
The maximal speed is equal to 155 rpm.
The torque sensitivity is equal to 37.5 Nm/Arms.
The permanent current I0of the motor is 130 Arms for 4870 Nm at low speed.
The nominal current Inof the motor is 129 Arms for 4800 Nm at the nominal speed.
Selection of the drive:
The drive has to provide at least a permanent current equal to I0(130 Arms).
In order to obtain an acceleration torque of 7000 Nm, the current will be about 190
Arms
(the motor data sheet shows 7200 Nm with 195 Arms). This means that the drive has
to provide at least 190 Arms as transient current.
Therefore, we can select the drive AC890 PARKERSD-43 3156 F which delivers
under 400 VAC:

Example n°3 :
This time, the application needs :
- a rms torque of 4500 Nm at the rms speed of 100 rpm,
- an acceleration torque of 5000 Nm,
- a maximal speed of 120 rpm.
Selection of the motor:
The selected motor is the type TMW306LR.
The nominal speed is equal to 125 rpm.
The maximal speed is equal to 155 rpm.
The torque sensitivity is equal to 37.5 Nm/Arms.
The permanent current I0 of the motor is 126 Arms for 4720Nm at low speed.
The nominal current In of the motor is 126 Arms for 4720 Nm at the nominal speed.
Selection of the drive:
The datasheet shows a torque sensitivity of 37.5 Nm/Arms. This means that the drive
has to provide at least 4500/37.5=106 Arms.
In order to obtain an acceleration torque of 5000 Nm, the current will be of about 133
Arms
(the motor data sheet shows 5190 Nm with 139 Arms). This means that the drive has
to provide at least 133 Arms as transient current.
Therefore, we can select the drive AC890 PARKERSD-43 3105 F which delivers
under 400Vac:
126 Arms as permanent current and
126*110%=138 Arms as maximal transient current during 60 s.
Under these conditions, the drive must run with “Quadratic as Servo Mode”.
The example n°3 illustrates the situation where the motor observes a “derating” mode
due to the current limitation set by the drive.
- the permanent torque authorized will be equal to 4720 Nm,
- the maximal transient torque will be equal to 5185 Nm during 60 s.

3.1.5. Current limitation at stall conditions (i.e. speed < 3 rpm)
Recommended reduced current at speed < 3 rpm:
Warning: The current must be limited to the prescribed values. If the
nominal torque has to be maintained at stop or low speed (< 3 rpm),
imperatively limit the current to 80% of I0(permanent current at low
speed), in order to avoid an excessive overheating of the motor.
Please refer to the drive technical documentation for any further
information and to choose functions to program the drive.
3.1.6. Peak current limitations
It is possible to use the TM motor with a current higher than the permanent current.
But, to avoid any overheating, the following rules must be respected.
1) The peak currents and peak torques given in the data sheet must never be
exceeded
2) The thermal equivalent torque must be respected (§3.1.3)
3) If 1) and 2) are respected (it can limit the peak current value or duration), the
peak current duration (tp) must be limited, in addition, accordingly to the
following table (Io is the permanent current at low speed):
Ip/Io =2
Ip/Io = 3
Ip/Io =4
Ip/Io =5
TMA
Tpeak < 4s
Tpeak < 1.7s
Tpeak < 0.9s
Tpeak < 0.5s
Ip/Io =1.5
Ip/Io = 2
Ip/Io =2.5
Ip/Io >2.5
TMW
Tpeak < 2s
Tpeak < 0.8
Tpeak < 0.5s
Not allowed
The peak current duration is calculated for a temperature rise of 3°C
