No. But a pinned target can be tied up to become helpless
Just follow the logic bellow and necessary actions and your target can be pinned, bound and helpless.
You can give your opponent the pinned condition (see Conditions).
Despite pinning your opponent, you still only have the grappled
condition, but you lose your Dexterity bonus to AC.
Then followed by:
If you have your target pinned, otherwise restrained, or unconscious,
you can use rope to tie him up. This works like a pin effect, but the
DC to escape the bonds is equal to 20 + your Combat Maneuver Bonus
(instead of your CMD). The ropes do not need to make a check every
round to maintain the pin. If you are grappling the target, you can
attempt to tie him up in ropes, but doing so requires a combat
maneuver check at a –10 penalty. If the DC to escape from these
bindings is higher than 20 + the target's CMB, the target cannot
escape from the bonds, even with a natural 20 on the check.
What does being tied up mean?
A creature that is tied up is "bound" which means it has the Helpless
condition. A helpless target is treated as having a Dex of 0 (–5
modifier). Melee attacks against a helpless target get a +4 bonus
(equivalent to attacking a prone target). Ranged attacks get no
special bonus against helpless targets. Rogues can sneak attack
