 Example:
When Pr.02-53 displays 0003h (hex), it means that RY1 and RY2 are used by PLC.

Preheating Output Current Level

Settings
 When a motor drive is not in operation (STOP) and is placed in a cold and humid environment,
enabling the preheating function to output DC current to heat up the motor drive can prevent the
invasion of humidity into the motor drive, which creates condensation affects the normal function
of the motor drive.
 Sets the output current level from the motor drive to the motor after enabling the preheating. The
percentage of the preheating DC current is 100% of the rated current of the motor drive (Pr.05-01,
Pr.05-13 and Pr.05-34). When setting this parameter, slowly increase the percentage to reach
the sufficient preheating temperature.
Preheating Output Cycle

Settings
Sets the output current cycle of preheating. 0–100% corresponds to 0–10 seconds. When set to

0%, there is no output current. When set to 100%, there is a continuous output. For example,
when set to 50%, a cycle of preheating goes from OFF (5 seconds) to ON (5 seconds), and vice
versa.
