Set drive parameter F6-32 = 0 to use PPO type formats. The PPO is defined for cyclic data transfer, allowing the

master and the slave to exchange process data (PZD) and parameters.

The option supports five possible PPO type formats:

• PPO type 1 (8 octets PKW + 4 octets PZD)

• PPO type 2 (8 octets PKW + 12 octets PZD)

• PPO type 3 (4 octets PZD)

• PPO type 4 (12 octets PZD)

• PPO type 5 (8 octets PKW + 20 octets PZD)

All PPO Types have the registers STW, ZSW, HSW, and HIW. These registers are not mapped directly to drive

registers.
