The below represents frequent questions our support, engineering and sales teams have been asked over the years. If you have a question, please submit our contact us form to reach our application engineering team.

Which firmware is required for S600 with Ethercat? [ S600 ]

EtherCAT works from firmware version 6.43. Firmware Versions 7.xx cannot be used.

Which firmware is required for S600 with SynqNet? [ S600 ]

SynqNet requires always a special firmware version. Please ask the Kollmorgen Support for this file.

When does the fan run if a fan option card is built-in? [ S600 ]

Fan on:
     Heat sink temperature > 65°C or environment temperature > 58°C or brake power > 30 Watts

Fan off:
    Heat sink temperature < 60°C and environment temperature < 55°C and brake power < 20 Watts

What is the life expectancy of the EEPROM? [ S600 ]

1 million data saves or 20 years

What is the average lifetime MTBF of the S600? [ S600 ]

For the whole S600 family the value is 290,000 hours.

Is it possible to load the current firmware into an old S600 (Ser.No. < 220.000)? [ S600 ]

No, the firmware version for S600 with serial number < 220.000 must be < 4.00

If the I2T value is shown in the S600 oscilloscope then the units are increments. What's the reason for that? [ S600 ]

The I2t resolution is built from: 

Scaling i2t = 688537600 in the scope is 100% I2T if ICONT = DICONT of the amplifier. 

If ICONT is 0.5 DICONT for example, then the value is 688537600 * 0.5 * 0.5.

If FOLDTIME differs from the default value 16 ms for example, this has influence to the calculation as well: 

688537600 * (ICONT/ DICONT)^2 * FOLDTIME / 16

How many slave S600s can be connected to one master S600 (electronic gearing, X5)? [ S600 ]

You can operate up to 15 slaves with one master.

How long can the S600 be charged with more than its rated output current? [ S600 ]

t = -17.4 * ln (1.0 - SQR(ICONT/I))

Example:
Inenn = 20 A (Typ S620)
Iist = 30 A
t = -17.4 * ln (1.0 - SQR(20/30))
t = -17.4 * ln (1.0 - 4/9)
t = -17.4 * ln (5 / 9)
t = -17.4 * (-0.587787)
t = 10.22 sec

How can I use the AS Option? [ S600 ]
  1. Parameters to set
    STOPMODE 1
    (0 default)
    If the drive is disabled, the amplifier switches to velocity mode and breakes with the ramp DECDIS. When the velocity VEL0 is reached, the power stage becomes disabled.
    ACTFAULT 1
    (1 default)
    If an error occurs, the amplifier switches to velocity mode and breakes with the ramp DECSTOP. When the velocity VEL0 is reached, the power stage becomes disabled. Exceptions are amoung others overvoltage and motor phase fault. In these cases a procedur like this would case additional problems.
    O1MODE 21 High with active power stage / Low with disabled power stage
    EMRTO
    (5000 Default)
    If the drive does not brake or the velocity does not reach VELO then the power stage will disable after this time.

    If setting of these time is too small, then the motor will never be braked down. For this reason DECDIS and DECSTOP must be realistic values and EMRGTO must be larger than DECDIS and DECSTOP.

  2. Process: switch off

    Disable the drive - The motor will be braked with DECDIS. Power stage disables. Output 1 switches to low.
    Switch 24V to the AS Enable input.
     
  3. Process: restart

    Switch off 24V from AS Enable.
    Switch Enable (HW and SW).
Can I reduce the fan noise? [ S600 ]

We offer an option card for the option slot in the S610...620 an. The device must be opened for the installation of this card, therefore the customer can't do that by himself without loosing warranty.

The card ist wired to the fam terminal in the amplifier and the fan is wired to the option card.

Why does the Multidrive communication not work? [ S400 ], [ S600 ]
  • Multidrive is not selected in the setup software
  • Master axis does not have ADDR 8
  • Different CAN baud rates are set
What is the current supply at the SinCos encoder interface? [ S400 ], [ S600 ]

At connector X1 there are 5V/150 mA available. These values are nominal even at maximum load. If a higher current is required, we offer an external power supply (350 mA) with a 1m cable. See instructions manual.

What are the maximum ramp times? [ S400 ], [ S600 ]

The maximum ramp time in a motion task can be calculated by: 

t{ms} = 140/32 x nsetp with PRBASE 16, 20 oder 
t{ms} = 140/32 x 16 x nsetp with PRBASE = 24.

Reduction while braking: tmax = 8000ms
Speed controller: t{ms} = 140 x 128 x n{rpm}

Is it possible to communicate with several servo amplifiers simultaneously via RS232 (Multidrive)? [ S400 ], [ S600 ]

Serial Communication via RS232 physically works with one amplifier only, but if you have connected several amplifiers via CAN bus to the "first" amplifier, you can communicate with all of them via RS232. This works either with the setup software (Multidrive must be selected) or with e terminal program (see page Multidrive Communication via RS232).

I have a motor, that is not listed in the motor database and that has no name plate. How can I setup this motor? [ S400 ], [ S600 ]

If the motor has a Resolver feedback, the page Setup of unknown motors describes the process.

I can't find my EnDat Motor in the motor database. What can I do? [ S400 ], [ S600 ]

Limit Ipeak and make sure, that no damage can occur even if the motor runs off.

Example 1: The motor type is not listed at all:

  • Select FBTYPE = 4, SAVE, COLDSTART
  • Read MPHASE, set MNUMBER = 0, SAVE; HSAVE and COLDSTART.

After rebooting, check MPHASE. If MPHASE no longer matches the original value, the source value must be set. Now all the motor parameters have to be determined.

Example 2: The motor is listed as a motor with resolver:

  • Select FBTYPE = 4, SAVE, COLDSTART
  • Read MPHASE, set MNUMBER = 0, SAVE; HSAVE and COLDSTART.
  • FBTYPE = 0, SAVE, and COLDSTART. Then select the appropriate resolver motor and save with SAVE, then COLDSTART.
  • FBTYPE = 4, SAVE and COLDSTART.

After rebooting, check MPHASE. If MPHASE no longer matches the original value, the source value must be set.

How many axes can be supplied by a master module? [ S400 ]

7 axes additional to the master axis.

How long is the reaction time for position latch and what happens while latching? [ S400 ], [ S600 ]

20µs with a jitter of 1µs.

The moment of the position latching is determined. With the next cycle of the position controller the (T=250µs) the latch position is calculated. High speed deviation in this cycle can lead to determination errors.

How can K and S be deactivated? [ S400 ]

Presumption is FW >7.22. 

DRVCFG2 = -2147483648 (= -2^31, set bit 31).
