DS2000 USER’S MANUAL (rev.C)
I.4
I.1 INTRODUCTION
This manual refers to DS 2000 “The Motion Solution” drive, with SW Release 3.20X.
The manuals from 0 to 3 release refers to DS2000 drives and SW release below 2.00X.
The manuals from 4 to 5 release refers to DS2000 “The Motion Solution” drive, with SW
release 3.00X and 3.10X.
New characteristics and added functionalities on DS2000 Software Release 3.200:
• I2T IGBT Protection. This functionality allows to protect IGBT modules from overheating,
due to excessive phase current flowing (particularly at low frequencies or locked rotor).
When the protection activates the drive can be disabled or the current flowing can be
limited. This functionality can be activated or deactivated from menu. Activating this
protection the Notch Filter will be automatically deactivated. I2T IGBT Protection and
NOTCH FILTER cannot be used together.
• Anti-Free-Wheeling (AFW). This functionality allows to have an emergency motor stop in
case of NO POWER, MOTOR OVERHEATING and DRIVE OVERHEATING. The motor
will brake with the deceleration value eventually set in menu. This functionality can be
activated or deactivated from menu.
• Regen Resistor Protection. Some customer applications have shown an intense
continuous utilization of the regen resistor that sometimes ends with its damage or even
breaking. To avoid this problem a new functionality has been developed within the new
DS2000 Firmware Release 3.200: this algorithm estimates the growing of the resistor
temperature and, depending on the manufacturer data (nominal power, maximum power
and time at peak power), protects it from dangerous overheating.
• FAS G Defluxing. This modification improves motor performances at high speed
introducing a defluxing component (sinusoidal current phase shifting) starting from a
speed value and with a maximum angle value to be set in the menu. This functionality can
be activated or deactivated from menu using its related parameter.
• Dead Band on analog reference. A dead Band on analog reference can be introduced
(centered on zero crossing and symmetric in both directions) with an amplitude selected
with the menu. It eliminates possible offsets that can cause slow motor shaft drift
rotations. This functionality can be activated or deactivated from menu using its related
parameter.
• PTC/NTC Selection. PTC/NTC motor thermal sensor can be selected using menu.
• Automatic Current Offset Compensation. This functionality automatically auto-activates
when drive is disabled and it repeats its calculations until the drive is off. When the drive
is enable, the last calculated offset value is memorized and used in current loop. When
the drive is disabled again, this function activates and compensates also possible thermal
drifts.
