Using VS-616G5 Drive Register 001h
When the drive is setup to receive Operation Signals from the MB+ Network, VS-616G5 Drive
Register 001h is used to operate the drive. This register performs multiple functions. Each of the
first 10 bits of this register serves a different purpose. The remaining bits of this register are not
used. The following diagram shows the function of each of the bits of this register. Bit 0 is the
least significant bit of the register. Bit 15 is the most significant bit of the register.
Bit Number 1
5 1
4 1
3 1
2 1
1 1
0 9 8 7 6 5 4 3 2 1 0
Bit 0 is used to start and stop the forward operation of the drive. To command the drive to stop
forward, this bit should be set to a ‘0’. To command the drive to run forward, this bit should be set
to a ‘1’.
Bit 1 is used to start and stop the reverse operation of the drive. To command the drive to stop
reverse, this bit should be set to a ‘0’. To command the drive to run reverse, this bit should be set
to a ‘1’.
Bit 2 is used to select the function for terminal 3. The function for terminal 3 is determined by the
setting of parameter H1-01.
0 = stop forward
1 = run forward
0 = stop reverse
1 = run reverse
