Need help?Do you have a question about the York VSD 608 and is the answer not in the manual?
The following symbols are used in this document to alert the reader to specific situations.
The YORK OSCD uses a different approach to speed reduction compared to earlier variable speed products.
Two conditions to be met for speed reduction: Setpoint requirements and Stability requirements.
Drive not reducing speed, Stability limit adjustment, and Surge margin adjustment.
Covers current imbalance, overload, and high heatsink/baseplate temperatures for converters and inverters.
Includes precharge lockout, harmonic filter high baseplate temp, and high total demand distortion shutdowns.
Covers VSD DC bus voltage imbalance and over-voltage faults.
Addresses faults like initialization, current scale, logic board, communication, and low converter heatsink issues.
Details faults related to low inverter baseplate temp, phase gate driver, and precharge DC bus voltage imbalance.
Covers faults related to run signal, serial communications, single phase input, and stop contacts.
Groups Harmonic Filter overload, DC bus voltage, transformer, communication, power supply, and phase lock loop faults.
