T-Series/Commands/Set Hold Current/Motorized NMC Devices/Percentage Current Setting
The current is related to the data by the formula:
- Current = CurrentCapacity * CommandData / 100
The Command Data can be a value from 0 (no current) to 100 (max). CurrentCapacity is the hardware's maximum capability of output current.
To prevent damage, some devices limit the maximum output current to a lower value. In that case the valid range is 0 - Limit. Current limits are listed under the device specifications.
Some devices limit the voltage rather than the current. In this case the same formula can be used by replacing Current and CurrentCapacity with Voltage and PowerSupplyVoltage.
For example, the T-MCA has a CurrentCapacity of 2.5A. To apply a current of 0.5A to a motor, reverse the formula:
CommandData
- = Current / CurrentCapacity * 100
- = 0.5A / 2.5A * 100
- = 20
Therefore CommandData = 20.
