In order to use the Megatorque Motor System properly,
observe the following notes.
1. Matters to be attended to use the Driver Unit of the Megatorque Motor System
------ For prolonged use of the Driver Unit ------
1
Temperature
l Keep the ambient temperature of the Driver Unit within 0 to 50°C. You cannot use the Driver Unit in an
atmosphere over 50°C. Keep a clearance of 100 mm in upper and lower sides of the Driver Unit when it is
installed in an enclosure. If heat is build up on upper side of the Driver Unit, provide the ventilation
openings on the top or an air cool unit for environment to take the heat out easily.
(Measures against contamination are required for the ventilation openings.)
2
Protection against contamination and water
l Install the Driver Unit into an enclosure that complies with IP54 or better protection code. Protect the
Driver Unit from oil-mist, cutting oil, metal chips, and paint fume etc. Otherwise it may result in failures
of electric circuits of the Driver Unit.
(IP code is specified in IEC standard. This is to classify the protection level of enclosures from solid
contamination and water.)
3 Wiring / Ground
l Refer to the User's Manual for proper wiring.
l Take appropriate measures not to contaminate the Driver Unit when wiring or installing.
4
Storing
l Store the Driver Unit in a place at where it is not exposed to rain, water and harmful gas or liquid.
l Store the Driver Unit in a place at where it is not exposed to direct sun light. Keep the ambient
temperature and humidity as specified.
5
Limited number of times for overwriting data
l The Driver Unit uses an EEPROM for backup of the data and programs. Though the number of times to
overwrite the EEPROM is guaranteed to 500 000, it is still possible that the Driver Unit may be disabled
by an alarm for “EEPROM error (E2)” that is triggered by exceeded limits of the number of times for
overwriting because of frequent changes of the parameters and programs through master controllers.
In such a case, change setting of the parameter WM to 1 from 0 (initial setting) to kill the backup function
after setting basic parameters such as I/O and servo parameters.
6
Handling of In-position (IPOS) output signal
l Different from the conventional EE/EK, EM/EP and ESA Driver Units, IPOS output of ESB Driver Unit
opens when the following conditions are met under the IPOS mode (FW0).
1) Motor servo is off.
2) An alarm is on.
l Be sure to check the master controller so that its controlling function will not be affected when replacing
the conventional Driver Unit with ESB Driver Unit.
