Yaskawa CIMR-EB4A0 A1000 Drive
A partial 400 V-class A1000 ordering designation that requires the current code and enclosure suffix before hardware selection.
Key Information
CIMR-EB4A0 identifies the opening portion of a Yaskawa A1000 E-spec 400 V-class drive order number. It does not identify one unique power rating because the following current-capacity digits and construction suffix are absent.
The A1000 is a high-performance vector-control drive family for induction and permanent-magnet motors. Exact output current, motor power, dimensions, braking arrangement and protective devices must be taken from the complete nameplate code.
Functions
- Controls motor speed and torque using A1000 vector-control functions.
- Supports configurable digital, analog and communication-based machine commands.
- Provides drive protection, diagnostics and parameterized acceleration/deceleration behavior.
- Integrates into industrial automation systems through the interfaces and options fitted to the complete drive.

Installation
- Read the complete CIMR code, input voltage, rated output current and enclosure designation from the drive nameplate.
- Size branch protection, cables, reactor and braking equipment for the completed model, not for CIMR-EB4A0 alone.
- Back up parameters, motor data, option-card settings and network addresses before replacement.
- Perform motor identification and a controlled direction, current and safety test after commissioning.
Lifecycle
- Do not convert CIMR-EB4A0 into a guessed power rating; multiple 400 V A1000 models share this prefix.
- Archive the complete order code, software version, parameter file and option-card list with the machine records.
- For migration to a current drive family, compare control mode, current rating, I/O, fieldbus and safety functions.
FAQ
Is CIMR-EB4A0 a complete Yaskawa order number?
No. CIMR-EB4A0 is a partial identifier; the current-capacity digits and construction suffix are required to select one drive.
Can the motor kW be determined from CIMR-EB4A0?
No. The missing current code determines the power class, so a nameplate photograph or complete CIMR number is necessary.
What information should accompany a CIMR-EB4A0 enquiry?
Provide the full nameplate, input voltage, rated current, motor data, enclosure, option cards, software version and parameter backup.
Can any 400 V A1000 replace a unit marked CIMR-EB4A0?
No. Current rating, overload duty, enclosure, braking, I/O and option compatibility must all match the installed application.
How should a CIMR-EB4A0-family drive be commissioned?
Restore only a verified parameter set, confirm motor data and option addressing, then test direction, current, braking and safety functions.
