16-Bit Counter; Master Control Start/Reset - Delta Electronics AC Motor Drive VFD-E User Manual

Mnemonic
CNT
Operand
Explanations:
1. When the CNT command is executed from OFF ON, which means that the counter coil
is driven, and 1 should thus be added to the counter's value; when the counter achieved
specific set value (value of counter = the setting value), motion of the contact is as follows:
2. If there is counting pulse input after counting is attained, the contacts and the counting
values will be unchanged. To re-count or to conduct the CLEAR motion, please use the
RST command.
